Abstract: This project consists in studying the transmission of heat produced in a cylinder through the ANSYS® simulation program in academic version. First, a brief explanation is presented about the operation of ANSYS® program and the steps followed to carry out the simulation. It is also verified that the program, in said version, is sufficiently capable of obtaining the desired results, carrying out a study on the meshing of the cylinder. This study shows that an error higher than 1.00% is obtained when using a mesh equal to or less than 418 nodes. Then, the dependency that shows the temperature as a function of time and dimensions is analysed, therefore obtaining the temperature profiles, the distribution and the time necessary to reach the steady state, this being 207 minutes. Later, the values obtained in the simulation are compared with the empirical equations and the laboratory practice performed in experimentation in chemical engineering I. The simulated model shows a good fit with the empirical model but a greater difference with the laboratory practice. This difference may be due to the fact that when the solid submerged, the water could have entered inside the cylinder causing an erroneous reading in the temperature, as shown by the values obtained during the experiment. Finally, the different simulation has been carried out to obtain the temperature range in which the laboratory practice could be performed, this being between 323.15 and 338.15 K
