... circular tube have been conducted with Lam–Bremhorst low Reynolds turbulence model. The present numerical investigations focus on the effects of the nitrogen content, heat flux, and flow orientation. Results indicate that as nitrogen content increases, the maximum heat transfer coefficient gradually...

... of the counterflow type vortex tube (RHVT). Experiments have been performed using oxygen ( O 2 ) , nitrogen ( N 2 ) , and argon (Ar). Five orifices have been fabricated and used during the experimental study with different nozzle numbers of 2, 3, 4, 5, and 6. The orifices used at these experiments are made...

...Antonio Campo; Salah Chikh; Mohammad M. Papari; Mohammad R. Mobinipouya This paper addresses the laminar boundary layer flow of certain binary gas mixtures along a heated flat plate. To form the binary gas mixtures, light helium (He) is the primary gas and the heavier secondary gases are nitrogen...

... in a subset of binary gas mixtures formed with helium (He) as the primary gas. The secondary gases are nitrogen ( N 2 ) , oxygen ( O 2 ) , carbon dioxide ( C O 2 ) , methane ( C H 4 ) , and xenon (Xe). The steady-state flow is governed by a system of 2-D coupled mass, momentum, and energy conservation...

.... Additionally, thin film temperature sensors were developed and used to directly measure the microchannel surface temperature. Heat transfer experiments were conducted with laminar nitrogen gas flow, in which the outlet Ma was between 0.10 and 0.42. The experimental measurements of inlet and outlet gas...

... the pressure sensitive paint (PSP) technique. Film cooling effectiveness distributions are obtained by comparing the difference of the measured oxygen concentration distributions with air and nitrogen as film cooling gas respectively and by applying the mass transfer analogy. Measurements are conducted...
