FEATool Heat Transfer Verification of a Multi-PCM Passive Vaccine Cold Chain Container
How long can a vaccine container stay cool without electricity? Researchers at the Technological Institute of the Philippines investigated a passive container designed to maintain a vaccine compartment between 2 and 8 °C for 17 days in a constant 35 °C environment. The design combines vacuum insulation with phase …
Cooling Effect of Adding Fins
This example models heated steam at a constant temperature of 120 C flowing through a aluminium pipe with 3 cm diameter. Heat loss to the surrounding cool air (at 25 C and heat transfer coefficient of h = 60 W/m2 C) is computed for a plain pipe, and also a pipe where 200 cooling fins per meter has been added. The …
Multi-Simulation Heat Exchanger
This tutorial model illustrates how one can couple the OpenFOAM CFD solver with the FEATool Multiphysics FEA solver. In the model a stream of cool air is heated while flowing through a tube and fin heat exchanger. Due to several symmetry planes only a small section of the full heat exchanger geometry actually needs to …
Heat Exchanger
This heat exchanger example illustrates the multiphysics modeling capabilities of FEATool. The model consists of a series of heated pipes surrounded by a fluid at a lower temperature, and features effects of both free and forced convection. Two types of physical phenomena are considered, fluid flow which is modeled by …
