Abstract:Extended AbstractWhen a solid surface in contact with a rarefied gas possesses a tangential temperature gradient, a thin Knudsen layer of the fluid adjacent to the surface will flow along with the gradient. This phenomenon is well known as thermal creep, which provides a mechanism for the thermophoresis of an aerosol particle in the slip-flow regime. Thermophoresis refers to the particle motion in response to a temperature gradient in the bulk gas against its direction. Being a mechanism for the capture of aer… Show more
