Time dependent simulation of the Driven Lid Cavity at High Reynolds Number

چکیده
In this work, numerical solutions of the two dimensional time dependent incompressible ow, in a driven cavity at high Reynolds number Re, are presented. At high Re, there is a controversy. Some studies predicted that the ow is steady, others found time dependent non-steady ow, either periodic or aperiodic. In this study, the driven lid cavity is successfully solved using a very ne grid mesh, for Re up to 30,000. We discretize the Vorticity-Stream formulation of the Navier-Stokes equation with nite di erences, in a 1025 x 1025 lattice. Using this very ne grid, the results obtained converge to a stationary solution. Detailed results for Re between 5,000 and 30,000 are presented.

Simulation of Lid Driven Cavity Flow at Different Aspect Ratios Using Single Relaxation Time Lattice Boltzmann Method
Abstract Due to restrictions on the choice of relaxation time in single relaxation time (SRT) models, simulation of flows is generally limited base on this method. In this paper, the SRT lattice Boltzmann equation was used to simulate lid driven cavity flow at different Reynolds numbers (100-5000) and three aspect ratios, K=1, 1.5 and 4. The point which is vital in convergence of this scheme ...

A numerical study has been done through an Al2O3–water in a double lid-driven square cavity with various inclination angles and discrete heat sources. The top and right moving walls are at low temperature. Half of the left and bottom walls are insulated and the temperatures of the other half are kept at high. A large number of simulations for a wide range of Richardson number ...

In this study, an adaptive neuro-fuzzy inference system (ANFIS) was developed to determine the Nusselt number (Nu) along a wavy wall in a lid-driven cavity under mixed convection regime. Firstly, the main data set of input/output vectors for training, checking and testing of the ANFIS was prepared based on the numerical results of the lattice Boltzmann method (LBM). Then, the ANFIS was develope...
