Tools for the design of heat transfer systems

This website is intended to be used as an online educational tool for the study of heat transfer and thermal problems. It can be used to calculate the heat transfer coefficient of several convection modes including single ant two-phase flows, to calculate frictional pressure drop, critical heat flux, flow pattern maps and to evaluate heat exchangers performance. For each parameter listed bellow, a page will be opened where reference models are presented and input forms are available to configure the calculation. The results are presented as numerical values or as graphical plots. Bellow are the links to the tools:
