... protection becomes better due to periodic jet disintegration into the wall surface caused by a higher level of transverse kinetic energy of the jet pulse. In addition, the overlapping of jet pulses appears to help the constant temporal spreading of coolant over the wall surface. For a higher mean blowing...

...Robert L. Jackson; Sushil H. Bhavnani; Timothy P. Ferguson A new multiscale model of thermal contact resistance (TCR) between real rough surfaces is presented, which builds on Archard’s multiscale description of surface roughness. The objective of this work is to construct the new model and use...

...Matthew J. Traum; Peter Griffith; Edwin L. Thomas; William A. Peters Microscale truss architectures provide high mechanical strength, light weight, and open porosity in polymer sheets. Liquid evaporation and transport of the resulting vapor through truss voids cool nearby surfaces. Thus, microtruss...

...Q. Z. Zhu; Z. M. Zhang Both one-dimensional (1D) and two-dimensional (2D) slope distributions were obtained from the surface topographic data, measured using an atomic force microscope for a rough silicon surface. The resulted slope distributions deviate significantly from the Gaussian distribution...

...H. G. Park; Morteza Gharib An experimental study is made on the processes of heat transfer from the surface of a forced oscillating cylinder in a crossflow. A range of oscillation amplitude A / D = 0.1 , 0.2 , forced oscillation frequency 0 < St c < 1 , and Reynolds number ( Re = 550 , 1100...
