Webb1 jan. 2009 · Both the mini-tunnel and the thermophoretic probe sampled from the same point in the exhaust line, where smoke opacity and gas temperature were also measured. The engine was tested under different engine speeds, air/fuel ratios and exhaust gas recirculation rates, to evaluate their independent effects on the morphology of the … WebbThermophoresis is particle motion induced by thermal gradients. Akin to other nonequilibrium transport processes such as thermal diffusion in …

Webb19 apr. 2024 · The experimental data show that the capture rates of DNA molecules decrease with increasing DNA length due to the thermophoretic effect of the molecules. … WebbThermophoresis has important applications in microparticle separation, colloidal crystal growth processes and other fields. Considering the unsteady variation of the temperature gradient in the fluid, the viewpoint that particles in fluids will experience thermophoretic impulsive force is proposed. The force is related to the particle motion in … jim click ford employment
