HEAT TRANSFER
 
BS EN ISO 10211-1 Test Case
Problem Definition
A three-dimensional heat transfer analysis of the models shown is carried out. Details of the geometry, material data and the applied convection conditions are provided within the standard: BS EN ISO 10211-1: Test Case 3. This standard states that:
  1. the difference between the temperatures calculated by the method being validated and the temperatures listed shall not exceed 0.1 K
  2. the difference between the heat flows calculated by the method being validated and the temperatures listed shall not exceed 2% of the listed values.
Solution Type: 3D Steady State Conduction and Convection
Elements: 3D Hex20 Brick Elements
Attributes: Ambient Temperatures and Convection Coefficients
