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 …
Battery-Free Solar PCM Tomato Cold Storage with FEATool
Keeping harvested tomatoes cool is difficult in off-grid tropical regions, where high ambient temperatures accelerate deterioration but reliable electricity may not be available. Solar-powered refrigeration can provide daytime cooling, but maintaining low temperatures after sunset commonly requires electrochemical …
Rocket Nozzle Design and Validation with FEATool Multiphysics
Small sugar-propellant rocket motors, often called R-Candy motors, provide an accessible platform for studying propulsion and nozzle design. Their relatively simple construction makes them suitable for educational and experimental rocketry, but predicting how combustion pressure, temperature, and exhaust flow interact …
Cooling Analysis of a Battery Pack Module
This example shows how to model a battery pack stacked with 20 prismatic battery cells. A heat transfer analysis will be conducted for the model where it is assumed that one of the battery cells is faulty resulting in significantly increased heat generation in the cell. Two different cases will be studied, one where …
Heat Conduction with Tabulated Thermal Conductivity
This heat conduction tutorial example illustrates how to use data from a (text) file in an equation coefficient. The tabulated data here represents non-linear thermal conductivity as a function of temperature k = f(T). Where the conductivity curve is given as sin(pi/8) to sin(3/4*pi) for temperature values between 280 …
ADRANOS simulation framework using FEATool Multiphysics
ADRANOS (short for Advanced Divertor paRametric Analysis for coolaNt Operating Scenarios) is a specialized MATLAB based simulation tool, developer by researchers at the Department of Engineering of the University of Palermo, to assess steady-state performance diverter cooling circuits in fusion reactor applications. …
Temperature Loading of a Tapered Cylinder
This validation test case models temperature loading of a tapered hollow thick cylinder with a spherical bottom flange section. The solid object is assumed to be clamped vertically, but allowed to expand horizontally due to a linear temperature gradient. The stress in the z-direction at the bottom inner point is …
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 …
Space-Time Transformation of Heat Conduction
This example considers transient heat diffusion in a solid 1 m rod where one end is kept at T = 25 degrees and the other subject to constant heat flux q_n = 1. This one-dimensional time dependent problem is transformed to a static two dimensional one. The computed results can both be compared with the analytical …
