Problem solving process for heat and mass transfer modeling

Normally in engineering, conceptual models provide formal model of the system. Mathematical modeling gives the systematic representation in terms of properties. Modeling process is performed by using design space analysis and mathematical equations and this can be performed with different design alternatives. Conceptual analysis of natural convection is described. In this paper the modeling of heat and mass transfer is performed with the concepts of heat and mass transfer and properties of objects in the design space. Numerical solution has been conducted for energy equation with different boundary conditions. The present work analyses the heat and mass transfer modeling process with mathematical equations.
