%0 Journal Article %T Governing equations of fluid mechanics in physical curvilinear coordinate system %A Swungho Lee %A Bharat K. Soni %J Electronic Journal of Differential Equations %D 1998 %I Texas State University %X This paper presents the development of unsteady three-dimensional incompressible Navier-Stokes and Reynolds-averaged Navier-Stokes equations in an unsteady physical curvilinear coordinate system. It is demonstrated that the numerical simulations based on governing equations in a physical curvilinear coordinate system are less mesh sensitive than other schemes. %K Physical curvilinear coordinate systems %K indent incompressible flows %K transformations. %U http://ejde.math.txstate.edu/conf-proc/01/l3/abstr.html
