Introduction to Numerical Methods in Cooling System Simulation 871463

The purpose of this paper is to present a numerical method for simulating single-phase or two-phase cooling systems, supposing available a model of the working fluid properties and of the cooling loop components. To make a computer simulation program one must be able to connect the analytical and physical aspects of the problem. This leads to a selection of certain quantities representative of the whole state loop (state variables). Also a method must be conceived enabling one to find the values of these state variables with regard to the imposed initial and boundary conditions.
An iterative method based on Newton-Raphson algorithm is used to solve the fluid-loop.
