URANS simulation of flow over smooth topography

A. Nakayama, K. Miyashita

An Unsteady Reynolds‐Averaged Navier‐Stokes (URANS) equation method has been applied to compute the flow over two‐dimensional smooth topography and compared with conventional RANS…

Application of genetic algorithms to the development of a variable Schmidt number model for jet‐in‐crossflows

Yanhu Guo, Guangbin He, Andrew T. Hsu

Proposes the use of genetic algorithms to assist the development of turbulence models. A variable Schmidt number model for scalar mixing in jet‐in‐crossflows was developed through…

Miscible displacement of a layer with finite width in porous media

Ching‐Yao Chen, Shu‐Wei Wang

Miscible displacement of a more viscous finite layer in porous media is simulated by means of high accuracy numerical schemes. Viscous fingers on the trailing front where the…

Convective heat and mass transfer in a visco‐elastic fluid flow through a porous medium over a stretching sheet

M. Subhas Abel, Sujit Kumar Khan, K.V. Prasad

Presents a numerical solution of the two‐dimensional laminar boundary layer problem on free and forced convection of an incompressible visco‐elastic fluid immersed in a porous…

Numerical analysis of the effects of tangential transpiration on the boundary layer characteristics

Burhan Çuhadaroğlu

In the present study, the characteristics of the turbulent boundary layer developing on a porous wall with various angles of injection and suction are analyzed numerically with…
