    Thermal - Radiation ambiant temperature

    Thank you IRstuff, Ambiant temperature may be non sequiture, but it is a input parameter for the computation of the surface to surface radiation in ansys, I also don't understand why and that is why I am asking this question. Furthermore, simulations showed that this parameter has an influence...

    Contact heat resistance

    Hello, I am currently working on the thermal assessment of a cubesat with ansys. I would like to implement in the model the contact heat resistance between the components of the satellite. Typical contacts are aluminium planes, bolted, with a surface roughness of ~Ra 3.2, and under vacuum...

    Bolted Joints in ANSYS

    Yes, it is common such methods with ansys to simplify the fasteners connections. You can use a "bushing" type of joint, then you can defines the stiffness coefficients in each directions. The Ansys help describes the procedure to apply it, here is the path: // Mechanical Application User's...

    Thermal - Radiation ambiant temperature

    Hi all, I am currently working on the thermal assessment of a cubesat with Ansys 14. I want to simulate the radiative heat transfer inside the satellite (between the different components. For that I set a surface to surface radiation, input the emissivity etc... My problem is: what is the...
