The 2D simulation shows that the mass transport in the test strip, in the heterogeneous case, seems to be slow, but the adsorption kinetics seem to be the rate-determining step anyway. The flow seems to quickly distribute the sample over the test strip. The results of the simulation after a temperature increase of 50 mK. Finally, we test a temperature difference of 2 K. The temperature and velocity fields are distinctly coupled and the fluid accelerates at the surface where the temperature gradient is highest. The results of the simulation when the temperature difference is raised to 2 K.

With the software, this simulation can be done in two ways: modeling wave propagation that includes a background flow or modeling the effects of high-power nonlinear acoustics. It is possible to solve for transient linear acoustics in a simulation that contains many wavelengths in a stationary background flow by modeling the convected wave .
Your pressure drop is virtually nothing, less than 1Pa, so the differences you see can be deemed to be tantamount to oscillations around the zero. You may want to try a 2D-axisymmetric model with a much finer mesh. Cheers I'm trying to calculate a pressure drop using laminar flow in comsol. I started with a simple model (see attachment). We can also perform a time-dependent analysis of the same model. The total time of the simulation is set to be 20 minutes and the base of the heat sink experiences 1 watt of heat flux during the entire simulation time. The relative tolerance of the solver is set to 0.001. The results of this simulation can be seen in the following animation. The Primary Current Distribution and Secondary Current Distribution physics interfaces in COMSOL Multiphysics solve Ohm’s law to predict the magnitude of this voltage, usually called the ohmic drop, as a function of electrolyte conductivity and electrode geometry.
