Simulasi CFD Persamaan Navier Stokes Untuk Aliran Fluida Tunak Laminar di Antara Plat Sejajar

Abstract

Real fluid behavior requires a distinction between the boundary layer, where stress effects are concentrated and areas where the potential flow of ideal flow hypothesis is fulfilled. Analysis of flow between two plates, an analysis for fluid flow flowing. Knowing the velocity distribution of fluid flow and pressure drop between two parallel plates is one common phenomenon. Navier -Stokes model used in predicting pressure drop and velocity distribution in this phenomenon. Simulation of fluid flow between two plates of the fluid is gliceryn with temperature is 20oC and density (rho) = 1260 kg/m3, dynamic viscosity (eta) = 1,5 N.s/m2 and Vin = 1 m/s and 2 m/s with the assumption that steady state and distance between the plates is 1 m and 0.5 m and length 20 m. In CFD simulations using software Comsol Multiphysics 3.5a and Matlab 7.9.
