WebJan 1, 2013 · Since the area of the triangular cell is the algebraic sum of A1, A2 and A3, the solid of revolution by rotating the triangle ABC about z-axis by 360 degrees could be determined by the combination of three circular truncated … Convection. A type of natural convection that can be described by the Navier–Stokes equation is the Rayleigh–Bénard convection. It is one of the most commonly studied convection phenomena because of its analytical and experimental accessibility. Exact solutions of the Navier–Stokes equations See more The Navier–Stokes equations are partial differential equations which describe the motion of viscous fluid substances, named after French engineer and physicist Claude-Louis Navier and Anglo-Irish physicist and … See more The Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is where • $${\textstyle {\frac {\mathrm {D} }{\mathrm {D} t}}}$$ is … See more The incompressible momentum Navier–Stokes equation results from the following assumptions on the Cauchy stress tensor: See more Taking the curl of the incompressible Navier–Stokes equation results in the elimination of pressure. This is especially easy to see if 2D … See more The solution of the equations is a flow velocity. It is a vector field—to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those of the velocity of the fluid at that point in space and at that moment in time. It … See more Remark: here, the deviatoric stress tensor is denoted $${\textstyle {\boldsymbol {\sigma }}}$$ (instead of $${\textstyle {\boldsymbol {\tau }}}$$ as it was in the general continuum equations and in the incompressible flow section). The compressible … See more The Navier–Stokes equations are strictly a statement of the balance of momentum. To fully describe fluid flow, more information is needed, how much depending on the assumptions made. This additional information may include boundary data ( See more WebThe objective of this study is to solve the two-dimensional heat transfer problem in cylindrical coordinates using the Finite Difference Method. From a computational code built in Fortran, the numerical results are presented and the efficiency of the proposed formulation is proven from three numerical applications, and in two of the numerical … smp interact
