摘要：
In this report, we consider and analyze the stability of implicit/explicit schemes for the natural convection equations, three kinds of numerical schemes are developed, which contain the Crank-Nicolson IMEX and BDF2-Adams-Bashforth (BDF2-AB) schemes. All numerical schemes treat the linear terms implicitly and the nonlinear terms explicitly, then the original nonlinear problem transforms into two linearized problems with constant coefficient matrix, the complexity of the calculation is reduced and a lot of storage is saved. The biggest feature of this work is the unconditional stability of the IMEX schemes for natural convection equations, which improves and supplements the published theoretical findings. Finally, some numerical examples are provided to show the performances of the considered numerical schemes.
