...Prasheel Nakate; Banjara Kotresha; N. Gnanasekaran In this work, a solution technique is proposed by synergistically combining asymptotics and computational fluid dynamics to ascertain a problem of laminar mixed convection heat transfer in a vertical channel. First, numerical simulation is carried...

... Heat transfer from a wedge to fluids at any Prandtl number can be predicted using the asymptotic model. In the asymptotic model, the dependent parameter Nu x /Re x 1/2 has two asymptotes. The first asymptote is Nu x /Re x 1/2 Pr→0 that corresponds to very small value of the independent parameter...

...M. M. Awad; S. D. Butt A simple semitheoretical method for calculating the two-phase frictional pressure gradient in porous media using asymptotic analysis is presented. The two-phase frictional pressure gradient is expressed in terms of the asymptotic single-phase frictional pressure gradients...
