It is presented in this thesis, a proposal for solution of engineering problems in heat transfer area using the network simulation method (NSM - Network Simulation Method), which is to solve these problems by analogy between the thermal circuits and electrical circuits. It will be presented to validate the two-dimensional problem of heat conduction in a cylinder in which the solutions obtained by simulation with the solution analytically obtained via Technical Generalized Integral Transform will face (GITT). In the simulations makes up the body discretization study with the aim of establishing a correlation between the amount of cells (the mesh refinement) and the relationship between the radius of the size and length of the cylinder so that the problem solution of heat transfer in the body can be considered one-dimensional. A comparison will be made between the analytical response and obtained by simulation, varying the number of divisions and different relationships between beam dimensions and length of the cylinder. From the solution validated the proposed method, applying the work presented as a generic fabric prepared by the NSM and implementation PSPICE, which serves for solving many problems of heat conduction in a cylindrical geometry.
