Web21 de jan. de 2024 · Table 2: The selection of time-dependent behavior of the problem should be appropriately selected for the numerical schemes. The first order bounded, ‘Euler’ is the most robust while the second-order ones are more accurate. Backward is a second-order time-differentiation scheme that gives higher accuracy but may reduce stability. Web1 de jan. de 2024 · D’Alessandro et al. [10] extended both methods to flow with heat transfer. Together with a Butcher tableau [6] for a family of Explicit RK (ERK) and Diagonally Implicit RK (DIRK) temporal schemes, Komen et al. [20] implemented the numerical approaches of Vuorinen et al. [43], Kazemi-Kamyab et al. [18], and D’Alessandro et al. …
