Applications of a flowfield-dependent mixed explicit-implicit (FDMEI) method to heat and fluid dynamics problems

Comparisons of a flowfield-dependent mixed explicit-implicit (FDMEI) method with other numerical schemes and experimental data are presented Several b enckmark examples are investigated to confirm the soluton accuracy and stab ility through more careful comparisons. In the FDMEI method, the implicitne ss parameters dictate the schemes which are adjusted to the physical phenom ena, compared with other numerical schemes dictated by arbitrarily selected constant parameters. Thus, tendencies of the implicitness parameters are d ependent on the flow, field. However, the implicitness parameters are more dependent on the flowfield in high-speed flows than in low-speed flows. Num erical results show that the FDMEI method is superior to other numerical sc hemes in accuracy and stability in all speed regimes, resolving shocks and vortexes.
