In our first lab, we used COMSOL multiphysics for the first time to examine the heat distrubution and current seen in an L-shaped Busbar.
Pictured above is the Busbar in its base form.
While editing the materials for the Busbar, we set the base material to be copper, and the bolts to be titanium. Since both materials have different conductivity and heat conductance, our procedure will lead to some differing results.
Pictured is the busbar with a mesh pattern implemented to it.
Here we have the heat distribution across the surface of the busbar. The heat along the copper surface appears to be largely the same, however the heat along the titanium bolts is different. The bottom bolts are evenly distributing heat of around 325 kelvin, while the top bolt is the hottest at over 330 Kelvin.
Finally we examine the current over the surface area of the busbar in A/m^2. The current appears almost like the heat, but appears more warped and distorted. Similar to the heat distribution, the bottom bolts have an even distribution of surface current of approimately 0.7x10^6 Amps, and the top bolt conducts the most at approximately 1 Megamp.
