The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications. It is primarily designed to solve partial differential equations (PDEs) of compressible hydrodynamics and has lots of add-ons ra

Thermophoresis and its effect on particle impaction on a cylinder for low and moderate Reynolds numbers

Autor: Ewa Karchniwy, Adam Klimanek, Jonas Krüger, Jørgen R. Aarnes, Nils Erland L. Haugen

Publikováno v: International Journal of Heat and Mass Transfer

The effect of thermophoresis on the impaction of particles on a cylinder is investigated for different particle sizes, particle conductivities, temperature gradients and for Reynolds numbers between 100 and 1600. This is the first such study performe

The effect of turbulence on mass transfer in solid fuel combustion: RANS model

Autor: Ewa Karchniwy, Sławomir Sładek, Øyvind Langørgen, Nils Erland L. Haugen, Adam Klimanek

Publikováno v: Combustion and Flame

In this paper, a kinetic-diffusion surface combustion model is examined. The model is modified such that two effects of turbulence are included: 1) enhancement of the mass transfer due to relative velocity between particles and fluid and 2) reduction
