Heat Transfer through a Steel Cooling Spine
Heat Transfer through a Steel Cooling Spine
The idea is to show how an insulated fin exactly works and if ANSYS AIM is good enough for simulations. The analysis done here is upon a Steel Cooling Spine that is used to cool a certain body. The conditions here are that if the body were 100 F under steady state conditions, the heat transfer coefficient for convection is defined as 2.778E-04 BTU/s.ft2.F and the ambient temperature of the air is 0 F. The ANSYS AIM analysis is to be compared to the calculation of fin with an insulated tip.
Geometry and Meshing
Geometry and Meshing
Geometry is made within the ModelDesigner in the ANSYS AIM with the dimensions as 1.2 x 1.2 x 8 in3.
Mesh was created with the mesh density of 2/7.
Constraints
Constraints
The constraint applied here is the body temperature that is 100 F and for the other tip which is insulated is simply left without any changes.
The rest of the walls are provided a convectional heat transfer coefficient which is 2.778E-04 BTU/s.ft2.F.

The Heat Flux Magnitude is presented with the Vector Graph. The Vector Graph shows the direction of the Heat flux in addition with the magnitude with the help of the range of colors used. The vector magnitude is the highest at the red color with the value as 0.64785 BTU/s.ft2 and the lowest magnitude at the blue color ith the value as 0.0063936 BTU/s.ft2.
This is simply another way of presenting the same information as the Vector Graph of the Heat Flux magnitude.
The Temperature Contour shows the temperature change within the body due to the steady state Convection at the surface of the Steel Spine and the Convection within the body of the Steel Spine. The temperature of the spine for one end was already known to be 100 F and the other is 72.405 F.
The calculation done here shows how the values converge to be one and the percentage error of 0.1145 %, too reflects how the ANSYS AIM is the perfect application for the Computer Simulation.
