摘  要:In this work we considered bi-domain partial differential equations(PDEs)with two coupling interface conditions.The one domain is corresponding to the ocean and the second is to the atmosphere.The two coupling conditions are used to linked the interaction between these two regions.As we know that almost every engineering problem modeled via PDEs.The analytical solutions of these kind of problems are not easy,so we use numerical approximations.In this study we discuss the two essential properties,namely mass conservation and stability analysis of two types of coupling interface conditions for the oceanatmosphere model.The coupling conditions arise in general circulation models used in climate simulations.The two coupling conditions are the Dirichlet-Neumann and bulk interface conditions.For the stability analysis,we use the Godunov-Ryabenkii theory of normal-mode analysis.The main empha-sis of this work is to study the numerical properties of coupling conditions and an important point is to maintain conservativity of the overall scheme.Furthermore,for the numerical approximation we use two methods,an explicit and implicit couplings.The implicit coupling have further two algorithms,monolithic algorithm and partitioned iterative algorithm.The partitioned iterative approach is complex as compared to the monolithic approach.In addition,the comparison of the numerical results are exhibited through graphical illustration and simulation results are drafted in tabular form to validate our theoretical investigation.The novel characteristics of the findings from this paper can be of great importance in science and ocean engineering.
