Thermophoretic Force and Velocity

III. Calculator

Now you have learned the important parameters that affect the thermophoretic force acting on a certain particle and the resultant thermophoretic velocity. Use the web-calculator below and try some values of the parameters to get your thermophoretic data. By using the same parameter values in both calculators while changing only one parameter value in one calculator, you can observe the effect of that parameter.

Below are thermal conductivities of certain materials. Try to change the thermal conductivity to see how it affects the thermophoretic force and velocity.

How do the following parameters affect the thermophoretic forces and velocities? (1) Particle size; (2) Particle's thermal conductivity; (3) Temperature gradient.
