| Popis: | The time requirements for the finite-difference computation of laminar natural convection in enclosures are so great as to preclude convergence by a preemptive reduction in the grid size. Computed results for one- and mo-dimensional natural convection are analyzed in order to evaluate the use of the hn method of Richardson and Gaunt for extrapolation of values for only one halving of the grid size. It is concluded that this method is applicable if a consistent order of truncation is used in alt of the finite-difference approximations and if the larger grid size is equal to or less than one-fifth of the least dimension. |
