Droplet evaporation is ubiquitous in everyday life and is essential in many industrial processes, such as inkjet printing, cleaning/coating of surfaces, and phase change heat transfer. This model demonstrates how to model phase transition by a moving exterior boundary condition using ... En savoir plus
Commercial heat exchangers often feature a complex design. It is significantly easier to build a design with new CAD parameters than to build designs with novel topologies. This model demonstrate how to optimize the size and position of the tubes in a tube and shell heat exchanger. It is ... En savoir plus
1D model of a thermal energy storage (TES) system consisting of a packed bed of pellets. Three approaches for heat transfer in porous media are compared: A one-equation local thermal equilibrium (LTE) model A two-equations local thermal nonequilibrium (LTNE) model A multiscale ... En savoir plus
This model demonstrates how to use the built-in shape optimization functionality to improve the performance of a plate heat exchanger. The optimization reduces the path immediately in front of the inlets and outlets to increase the length of typical streamlines. This leads to a improved ... En savoir plus
In this example, a heat transfer model of a fiber composite's unit cell is analyzed with the Cell Periodicity feature. The homogenized thermal conductivity, density and heat capacity of a composite material are computed based on the individual properties of fiber and matrix. A comparison ... En savoir plus
This tutorial presents the averaging models available within the Heat Transfer in Porous Media interface, used to compute the effective thermal conductivity, when the local thermal equilibrium assumption is made. The models are compared for porosities ranging from 0 to 1, and for a ... En savoir plus

Fluence rate is a key parameter for ultraviolet (UV) water purifier. It describes the amount of radiation that pathogens absorb and is then directly related to the disinfection level of the purifier. The aim of this example is to demonstrate the fluence rate calculation with the ... En savoir plus
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... En savoir plus
This model shows how to use the features of the Heat Transfer Module to reduce the computation time and memory usage in view factor computations. Illustrative results of speedup and memory usage reduction are given on a benchmark model. The solution is not computed, only the view ... En savoir plus
