WebbOpposite to the friction force, the thermophoretic force of a rod oriented with the temperature gradient can be larger or smaller than when oriented perpendicular to it. The … WebbThe contributing factors that affect the thermophoretic force in-clude the thermal conductivity of particles, the temperature of the gas and the flow regime. For the free molecular flow regime, the thermophoretic force increases as the pressure increases, whereas in the continuous flow regime the opposite effect occurs. The 2015 The …
WebbThe force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the cold side, which results in a net force towards cold areas. This effect can be exploited to create thermal … WebbExact solutions for some oscillating motions of an Oldroyd-B fluid due to an oscillating circular cylinder are established as Fourier–Bessel series in terms of some suitable eigenfunctions.These solutions, presented as sum of steady-state and transient solutions, reduce to the similar solutions for Maxwell, second grade and Newtonian fluids as …
Webb12 force exhibits a linear dependence. In fact, in the initial regime the magni-13 tude of the friction force increases linearly with the droplet velocity, until 14 the thermophoretic force is balanced by the friction force as the droplet 15 reaches its terminal velocity in the nal regime. In addition, an increasing 16 magnitude of the thermophoretic force is found for …
