Thermophoretic deposition of small particles in a direct numerical simulation of turbulent channel flow. (English) Zbl 0918.76088

Summary: We obtain some results by direct numerical simulation of a horizontal turbulent channel flow. A temperature profile typical of ceramic oxide aerosol reactors is imposed across the channel. Thermophoresis plays an important role in the deposition of particles for the range of conditions that are under consideration. An interaction between turbophoresis and thermophoresis is shown to play an important role in the deposition process.
