Webb19 jan. 2009 · Numerical results for the non-dimensional velocity, temperature and concentration profiles as well as the local skin-friction coefficient, the l ocal Nusselt number and the local Stanton number are presented for different physical parameters. The results show that variable viscosity significantly increases viscous dr ag and rate of heat … MST is based on the quantifiable detection of a fluorescence change in a sample when a temperature change is applied. The fluorescence of a target molecule can be extrinsic or intrinsic (aromatic amino acids) and is altered in temperature gradients due to two distinct effects. On the one hand temperature related intensity change (TRIC), which describes the intrinsic property of fluorophores to change their fluorescence intensity as a function of temperature. The extent of th…
WebbWe show that thermophoresis is related to the Soret effect. The thermophoretic force acting on a particle immersed in a fluid which has a temperature gradient, →∇ T, is given … WebbAdditionally, the thermophoretic driving force occurring in convection flow through a porous medium has attracted significant attention because of widely practical …
WebbIncluding Thermophoretic Force Effects on the Particles If you want to include the effect of the thermophoretic force on the particle trajectories ( this equation in the separate Theory Guide ), enable the Thermophoretic Force option under the Physical Models tab, in the Discrete Phase Model dialog box. Webb12 mars 2008 · By measuring the full temperature dependence of this effect for polystyrene latex suspensions, we show that the thermophoretic mobility (or “thermal diffusion coefficient”) DT is basically independent on particle size, in particular, when the interfacial properties of the colloidal particles are carefully standardized by adsorbing a surfactant …
