... at strategic locations within the flow field, which are determined by examining the CFD solution of a uniform grid. Three cases are examined, the backward-facing step, flow over an asymmetric transonic airfoil, and hydrogen combustion in a channel. Grid independent solutions are obtained for all three cases...

...Javier Ortiz-Villafuerte; Yassin A Hassan Particle tracking velocimetry has been used to measure the velocity fields of both continuous phase and dispersed microbubble phase, in a turbulent boundary layer, of a channel flow. Hydrogen and oxygen microbubbles were generated by electrolysis...

...Ashvin Hosangadi, Principal Scientist; Vineet Ahuja, Research Scientist Numerical simulations of cavitation in liquid nitrogen and liquid hydrogen are presented; they represent a broader class of problems where the fluid is operating close to its critical temperature and thermal effects...

...D. R. Buttsworth; T. V. Jones A new probe technique is introduced for the measurement of concentration in binary gas flows. The new technique is demonstrated through application of the probe in a Mach 4 nonreacting jet of hydrogen injected into a nominally quiescent air environment. Previous...
