... of the nozzle exit. The formulations of these unsteady flow structures, and its development into fully turbulent steady state flows are of interest to designers. Many PLIF experiments on the temporal development of jet flows revealed the existence of highly under-expanded flow, moderately under-expanded...

... cases. Already, evidence of the IDS capability is demonstrated in its simulating solution of the unsteady Rayleigh-Taylor problem. Keywords: Euler, Turbulent, Eddies, Integro-differential scheme, compressible flows. NOMENCLATURE The following symbols and indices are used in this article: dS [m2] Surface...

... are evaluated. Surface heights of 0.25, 0.5, 1, and 2 m are also assessed. For flow rates greater than 50 m/s, turbulent flow optimum nodule size is between 0.2 mm and 0.6 mm. Surfaces greater than 1 m in height at flow rates less than 50 m/s maximize mass with nodule sizes of 1.4 mm and 2 mm. hydrophilic...

... equations under realistic conditions. In the case of the compressible boundary layer, the IDS capture the flow field physics. However, it was demonstrated that the IDS is highly sensitive to grid resolution as well as the prescribed boundary conditions. laminar turbulent boundary layers integro...

... Turbulent flow of a Non-Newtonian polymer fluid through concentric annuli was studied using 9 m long horizontal flow loop (inner to outer pipe radius ratio = 0.4) and Particle Image Velocimetry (PIV) technique. A high molecular weight, anionic, water soluble, acrylamide-based copolymer was used...

... on the pressure drop and transition to turbulence is studied experimentally in a conventional channel of 1.9 cm inner diameter. Four types of entrance conditions have been studied with flow of oil in a closed loop. The experimental results show the effect of entrance conditions on local friction factor...
