PROJECT #2 Time Developing Flow in a Driven Cavity Project report due on December 1, 2014 Solve the incompressible Navier-Stokes equations in primitive variable form for the two-dimensional, two-sided lid-driven cavity problem. The lid-driven cavity is an important fluid mechanical system serving as a benchmark for testing numerical methods and for studying fundamental aspects of incompressible flows in confined volumes which are driven by the tangential motion of a bounding wall. Download Presentation Parallelization of 2D Lid-Driven Cavity Flow An Image/Link below is provided (as is) to download presentation. This project requires that the Vorticity streamline function, u and v velocity profiles, pressure contours for the lid driven rectangular cavity for Reynolds number 100 and 1000. This project aims at simulating lid driven cavity flow problem using package MATLAB. T1 - A reduced-order model of three-dimensional unsteady flow in a cavity based on the resolvent operator. 09:49 As an assignment- modify the grid size of the cavity. There are PCP pumps in the market that are called electrical submersible progressing cavity pumping systems, that are powered by an ESP motor. The objective of this project is to develop and apply a computer program to solve the two-dimensional unsteady Navier-Stokes equations for an elliptic flow in a square cavity with top wall sliding at a given velocity.

Flow in a Lid-Driven Cavity Introduction The purpose of this tutorial is to illustrate the setup and solution of the two-dimensional laminar fluid flow for a lid-driven cavity. com Abstract with a shroud. Here, we demonstrate how to define this benchmark. As a first installment, definitive benchmark results for the classic CFD 2-D lid-driven cavity flow problem are presented up to Re = 30000 (significantly more accurate than the existing literature for Re > 1000, unpublished and not available anywhere else). The stationary solution obtained is illustrated on Figure 59. Therefore, in the current computational study on 2-D incom-. From the dynamical systems theory stems that all solutions to this problem converge to a global attractor, an ensemble with many mathematical properties. 06:20 Now, after this, on top of the left-hand side on active variable control drop-down menu, change this from solid color to p or capital U which are the initial conditions such as pressure, velocity.
