Thermal Conductivity Plastic

Based on Ken Elder's 1993 paper: "Langevin simulations of nonequilibrium phenomena" Computers In Physics, vol. 7, no. 1, 1993, p.27-33.Domains of ordered phase are created from an initially disordered phase due to thermal fluctuations. The domains coarsen as a function of time. Large domains grow...

This heat exchanger exists of a pipe with a cold fluid that is heated up by means of a convective heat transfer from a hot condensate.

The project discusses the problematics of making a system of differential equations describing the transition processes in the operation of resistance furnaces, their realization through digital methods and the analysis of the achieved results. Solving of the problem thus formulated is carried...
