The transport equations of fluid mechanics are conservation equations. No other use or distribution of this Manual is permitted. However, you would be hard pressed to think of a physical situation in which a curved edge like that of Fig. ![]() This speeds up convergence because the gross features of the flow are quickly established on the coarse grid, and then the iteration process on the finer grid requires less time. Discussion Keep in mind that if the boundary conditions are not specified properly, or if the chosen turbulence model is not appropriate for the flow being simulated by CFD, no amount of grid refinement is going to make the solution more physically correct. Analysis The standard method to test for adequate grid resolution is to increase the resolution by a factor of 2 in all directions if feasible and repeat the simulation. Then, an artificial time is used to march the solution in time. Intervals represent the small edges of cells themselves. GEOFFREY BARRACLOUGH AN INTRODUCTION TO CONTEMPORARY HISTORY PDF This is the case with fluid mechanics since each component of velocity, for example, appears in the continuity equation and in all three components of the Navier-Stokes equation. Hence it is always wise to extend the downstream portion of the domain as far as necessary to avoid reverse flow problems at the outlet boundary. If, on the other hand, there are significant differences between the two solutions, the original grid is likely of inadequate resolution. The symmetry boundary condition merits further discussion. The edge cannot be a fan or interior because such edges cannot be at the outer boundary of a computational domain. The curved edge cannot be an axis because an axis must be a straight line. In cegel a case, an even finer grid should be tried until the grid is adequately resolved. These equations, when centel with the appropriate boundary conditions, are sufficient to solve the problem. Post processing is generally not as CPU intensive as the iterative process itself. Analysis Flow separates over bluff bodies, generating a wake with reverse flow and eddies downstream of the body. Calculate global and integral properties as needed. ![]() These initial conditions are wrong, of course, but they are necessary as a starting point.
