The effect of a non‐uniform temperature profile on the flow field in a continuous rotating annular electrophoresis column is investigated. The momentum balance equation is solved for packed as well as unpacked columns using a centered‐difference finite difference technique with a known temperature profile. The packed column analysis utilizes a parallel annular channel model similar to the capillary channel model used in packed bed columns. Results indicate that the changes in density and viscosity as result of the temperature variation have a significant effect on the flow field. Effects of voltage gradient and column geometry are also discussed.
