    • CFD modelling of rectangular micro channel with increase in heat flux and effect on nusselt number 

      Gogineni, Aneesha (Wichita State University. Graduate School, 2010-04-23)
      A laminar convective heat transfer coefficient of a rectangular microchannel is investigated under constant heat flux value throughout the wall. Two dimensional numerical simulations were performed using the FLUENT and ...
    • Computational simulation of the atmospheric boundary layer using sub-optimal grid resolution 

      McKenna, Matthew (Wichita State University, 2018-05)
      This study explores simulation of turbulent atmospheric boundary layer (ABL) flow fields using reduced mesh resolution as a means for reducing time and computational requirements. A full resolution simulation is performed ...
    • Fatigue behavior of plasma spray coatings on polymer matrix composite materials 

      Haqu, Ziaul (Wichita State University, 2008-12)
      The majority of coated structural components are subjected to fluctuating internal and/or applied stress because of oscillating mechanical loads. The fatigue behavior of coatings and the overall cyclic failure response of ...
    • Fatigue characterization of plasma spray coated composites 

      Haqu, Ziaul; Ahmed, Ikramuddin; Talia, Jorge E.; Asmatulu, Ramazan (American Society of Mechanical Engineers, 2012)
      In this work we study the fatigue behavior of plasma sprayed metallic coatings on graphite reinforced polymer matrix composites. In the absence of any standards for testing of coatings, the ASTM standard for composites was ...
    • Geothermal cooling system for a small house 

      Ranaweera, Dilmi T. (Wichita State University, 2021-04-02)
      With the rising cost of air conditioning, and the increasing environmental pollution caused by refrigerants, an alternative method for residential cooling needs to be considered. The objective of this research is to find ...
    • High Rayleigh number flows in a cubical enclosure 

      Bende, Balaraju (Wichita State University, 2010-12)
      The current study was undertaken with an intention to verify and extend the boundaries of the work produced by Xia & Murthy [24] and Vargas [23] on natural convective flows inside a cubical enclosure to observe the transition ...
    • Life cycle assessment of Solar Updraft Tower Power Plant: EROEI and GWP as a design tool 

      Zongker, James D. (Wichita State University, 2013-12)
      The Solar Updraft Tower Power Plant (SUTPP) is a simple proven concept capable of producing power from sunlight with relatively little complexity and few moving parts. Unfortunately, it requires a large investment to build ...
    • Plasma spray coatings for polymer composites 

      Diccar, Unmesh Vilas (2006-12)
      Thermal spray coating was studied as one of the techniques used for coating graphite reinforced polymer composites, which are extensively used in the aviation industry. These coatings were studied for improvement of surface ...
    • Protective thermal spray coatings for polymer matrix composites 

      Vyawahare, Suddharth M. (2006-12)
      Polymer matrix composites were coated with metals, alloys and intermetallic compounds using the thermal spray coating technology. Air plasma spraying and flame spraying were the two spraying techniques primarily used ...
    • Study of heat transfer from an impinging jet to a substrate 

      Pokharel, Arjun (2005-12)
      A high-temperature argon-hydrogen plasma jet issuing into ambient air and impinging on a flat circular steel substrate was modeled using a commercial CFD software. Plasma was represented as an ideal gas with temperature-dependent ...
    • Thermal conductivities of electrospun PAN and PVP nanocomposite fibers incorporated with MWCNTs and NiZn ferrite nanoparticles 

      Khan, Waseem Sabir; Asmatulu, Ramazan; Ahmed, Ikramuddin; Ravigururajan, Tiruvadi S. (Elsevier, 2013)
      Polyacrylonitrile (PAN) and polyvinylpyrrolidone (PVP) solutions incorporated with multi wall carbon nanotubes (MWCNTs) and NiZn ferrite (Ni0.6Zn0.4Fe2O4) nanoparticles were electrospun at various weight percentages, and ...
