thermal insulating vessel FEA finite element analysis
Thermal insulating vessel (thermal conductivity of the material is given) separates a heated agent from the ambient space so that temperature difference between its internal and external sides is 220°C.
Problem type: Axisymmetric problem of heat transfer.
Geometry:
r1=610 mm, r2=700 mm
Given:
Thermal conductivity of the material λ=0.083 W/(m·K);
Temperature of the external boundary T0;
Temperature of the internal boundary T0 + 220°C.
Task: Calculate heat flux passing through the spherical surface of the vessel.
Solution: The problem is linear, and passing flux will be the same for any specific setting of T0. For simplicity we may consider T0=0°C (273.15 K).
Result:
Heat Flux, W
