Analysis of temperature distribution and heat flow in the exhaust system of diesel engine to determine technical parameters of the system for heat recuperation and changing of thermal energy into electric energy was presented. Temperature of exhaust gases as well as geometrical and material features of exhaust system were the input data accepted for modelling. Computational Fluid Dynamics (CFD) was used to determine temperature distribution in the exhaust system. The software by use numerical methods finite volume method) enables solving partial differential equations consisting of equations of: continuity, Navier-Stokes, Fourier-Kirchoff and complemented with other equations important as regards the discussed phenomenon (e.g. with turbulences models)transforming them in the algebraic equations or common differential equations. CFD software enables gaining some information as regards flow rate, distribution of speed field, and pressure field as well as heat flow, temperature field and mass field. Design and principle of operation of Peltier 's cell, model of recuperator, exhaust system, and diesel engine, finite elements meshing, boundary conditions assumed in analysis of exhaust gases and water flow, distribution of temperature field (maximal temperature of scale 335 K and maximal temperature of scale 400 K) on external wall of exhaust system and cross-section of exhaust system are presented in the paper.
