    • Air ventilation and thermal comfort in a tramcar 

      Demir, U.; Angeneh, S.R.; Sagir, D.; Aktas, Murat Kadri (Avestia Publishing, 2019-08)
      In the present study, heating, ventilation and air conditioning (HVAC) vents of a tramcar passenger cabin were designed by utilizing computational fluid dynamics (CFD) analysis. Three dimensional and transient numerical ...
    • Computational fluid dynamics simulations of windage loss in a spur gear 

      Aktaş, Murat Kadri; Yavuz, Mehmet A.; Ersan, Ali K. (American Society of Mechanical Engineers (ASME), 2018)
      Windage losses arise due to the viscous dissipation of air - oil mist flow driven by the rotating faces, sides of the gears in a gearbox. The windage losses can consume up to 3% of the transmitted power. In the open ...
    • Effects of pulsating flow on convection in wavy channels with phase shift 

      Angeneh, S.R.; Baser, O.; Aktaş, Murat Kadri (Begell House Inc., 2020)
      Effects of pulsating flow on convective heat transfer in two-dimensional sinusoidal wavy passages are investigated numerically. A straight channel and three channels with wavy walls are considered. Phase shifts (? = 0°, ...
