  • PhD Related Data: THE ENHANCEMENT OF MECHANICAL DAMPING AND STIFFNESS TRADE-OFF USING UNIDIRECTIONAL CARBON FIBER REINFORCED POLYMER COMPOSITE INTERLEAVED WITH RECYCLED CARBON FIBER AND SHORT VIRGIN ARAMID FIBER NON-WOVEN MATS by Cephas Yaw Attahu
    This research investigated incorporating recycled carbon fibers (rCFs) into carbon fiber reinforced polymer composites (CFRPs) for structural applications. The impacts of titanate coupling agent-L12 on the mats; the interleaved rCFs mat's numbers; their locations (the interleaved rCFs mat); the influence of the rCFs' lengths and their combinations (combining different rCF lengths); types (different rCF types); and their (rCFs) micro-hybridization with short virgin aramid fibers (vAFs) were all explored as part of the investigations. This project addressed and closed a significant gap in using rCFs for structural applications. The methodology used (the interleaving of UD fiber/epoxy prepreg with rCF non-woven mats) is the first of its kind. Furthermore, the final product (the best configuration, Laminate T) was very competitive: it was pegged against another novel composite material from an excellent source, and the results were very encouraging. Hosted here is the project's related raw dataset.

  • Dataset on Integrated Solid Desiccant Packed Bed - Oscillating Heat Pipe Systems
    This experimental dataset for Integrated Solid Desiccant Packed Bed-Oscillating Heat Pipe System contains raw temperature data obtained from Fully Packed Bed (FPB), Small Annulus Packed Bed (SAPB), Medium Annulus Packed Bed (MAPB) and Large Annulus Packed Bed (LAPB) all respectively integrated with Helically Coiled Oscillating Heat Pipes (HCOHPs) charged respectively with Ethanol (EOHP), Methanol (MOHP), and Deionized Water (WOHP). The packed beds were filled with silica gel (Silicon Dioxide/SiO2) of particle size between 3.35mm-4.75mm. The annulus packed beds were in Heggs et al (1994) Z configurations described by their annular dimensions as small (SAPB), medium (MAPB) and large (LAPB) corresponding to diametrical ratios (Do/Di) of 2, 2.35 and 3.08, respectively. The data are mainly raw temperature data from Omega K-type thermocouples inserted in three designated Mass Transfer Zones (MTZ 1, MTZ 2 and MTZ 3), corresponding Walls (Wall 1, Wall 2, and Wall 3), Evaporators (Evap), Condensers (Cond), and Adiabatic Sections (Adiab) of each HCOHP integrated with a packed bed. Each packed bed was integrated with three (3) HCOHPs containing the same working fluid. Each HCOHP had two (2) thermocouples on their adiabatic sections and three (3) thermocouples installed on their evaporators and condensers respectively. The HCOHPs were numbered 1, 2 and 3 and the position of thermocouples on each component were labelled a, b, and c. For instance, the first evaporator would be labelled Evap_1 and where the thermocouple is located can be identified by say Evap_1a indicating the thermocouple is on the first position on the 1st evaporator. The ambient temperature data are also presented for each integrated system. The inlet and outlet pressures of each packed bed obtained as electrical pulses in Voltage and converted into Pascal (Pa) are captioned as Derived Pressure in Pa. Inlet and outlet air temperature, velocity and relative humidity obtained from Sentry ST732 Hotwire Anemometers and AZ 8829 Temperature and RH% data loggers are on the Inlet and Outlet Data Tabs. The dataset has seven (7) spreadsheets each for a packed bed configuration type integrated with the EOHP, MOHP or WOHP. For instance, for SAPB integrated with the HCOHPs i.e., EOHP, MOHP, and WOHP respectively, the combinations are SAPB-EOHP, SAPB-MOHP and SAPB-WOHP respectively. Each combination is presented on separate Tabs on the spreadsheet with its test run number such as SAPB-EOHP 1, SAPB-MOHP 1 and SAPB-WOHP 1 for test run 1 and SAPB-EOHP 2, SAPB-MOHP 2 and SAPB-WOHP 2 respectively for test run 2. The annulus packed bed configurations integrated with the HCOHPs have data for two test runs presented. Only one test run data is presented for the fully packed bed (FPB) namely FPB-EOHP, FPB-MOHP and FPB-WOHP respectively with respective inlet and outlet conditions data.

  • Simulation Dataset on Fire in the Cavity of Naturally Ventilated Double Skin Façade with Venetian Blinds
    This dataset contains thermocouple temperature data in °C obtained from Fire Dynamic Simulation (FDS) of a 5MW HRR polyurethane GM27 fire in a multi-storey Double Skin Façade (DSF) building with Venetian blinds. The Excel spreadsheet has temperature data obtained from thermocouples installed on the glazing surfaces in the DSF cavity for floors 2, 3 and 4 (see Physical Model and Thermocouple Map). The data is presented for the scenarios where there is no Venetian blind installed in the DSF cavity to when the Venetian blind is 0.5m away from the inner glazing, Middle and 0.5m away from the outer glazing in the DSF cavity. In these scenarios the dataset also shows the glazing surface temperatures for various Venetian blind slat angle openings of 135°, 90°, 45° and 0° in the three Venetian blind positions in the DSF cavity. The simulation was carried out at 100s per scenario. The dataset also contains the input and output data files obtained from the National Institute of Standards and Technology’s (NIST) Fire Dynamic Simulator (FDS) software used for the investigations. A PDF of the Physical Model and Thermocouple Position Map is also provided in this dataset to provide clarity for users of this dataset.

  • Dataset on Helically Coiled Oscillating Heat Pipe (HCOHP)
    This dataset contains raw primary temperature data obtained from the three HCOHPs charged with ethanol, methanol, and deionized water respectively and tested in the laboratory using three different heat inputs. The maximum heat input element temperatures were 100°C, 125°C and 192°C, for test Run 1, 2 and 3, respectively. The temperature data were obtained from three Omega K-type thermocouples attached to each condenser and evaporator of the HCOHP respectively, two attached to the adiabatic sections, and two attached to the inner and outer surfaces of the cylindrical copper vessel for the heat transfer. The other dataset is derived from the average temperatures from the raw primary temperature data. Here, relevant equations for the determination of the heat flux, power input, thermal contact resistance and overall thermal resistance was used. The data are presented on six separate Excel files. The first three files are captioned HCOHP Primary Data – Run 1, HCOHP Primary Data – Run 2, and HCOHP Primary Data – Run 3 representing raw primary temperature data for the three HCOHPs for each test run. The second three Excel files are captioned HCOHP Derived Data – Run 1, HCOHP Derived Data – Run 2, and HCOHP Derived Data – Run 3 represent the derived data obtained from the average raw primary temperature data for each test run. In the Excel files EOHP, MOHP and WOHP represents the ethanol charged HCOHP, methanol charged HCOHP and deionized water charged HCOHP, respectively.

  • Boxing2 Data
    This data set comes from purse information provided by the Nevada State Athletic Commission (NSAC) and the California State Athletic Commission (CSAC). The NSAC provided purse information on professional boxing matches in that state from 2009 to 2017. The CSAC provided purse information for the period June 2012 to December 2015 and its website provided purse information for 12 additional boxing cards held between 2016 and 2017, which are also included in the data set. After excluding female boxers and a few other minor exclusions, the result is an unbalanced panel of 1,212 boxers observed an average of 3.85 fights.

  • Data for: Electrical resistivity of pure copper processed by medium-powered laser powder bed fusion additive manufacturing for use in electromagnetic applications
    This data is from the research article entitled “Electrical resistivity of pure copper processed by medium-powered laser powder bed fusion additive manufacturing for use in electromagnetic applications” [in press]. This article presents data from a series of tests which were taken on rectangular 3D printed specimens in order to determine the electrical resistivity of the material. Variations to the specimens include different initial build orientations and different heat treatments to determine their effects on resistivity. Resistance measurements were taken along with the physical dimensions of each specimen.
