A multiscale model was developed for the channel of a CoAxial Magnetically Insulated Long Anode (CAMILA) Hall effect thruster. The computational domain was subdivided into a region where a hybrid solver is used and a region where a fully kinetic particle in cell s...

An analysis is given for fully developed thermal transport through a wall-bounded turbulent fluid with constant heat flux supplied at the boundary. The analysis proceeds from the averaged heat equation and utilizes, as principal tools, various scaling considerations. The paper first provides an accounting of the relative dominance of the three terms in that averaged equation, based on existing ...

Stability of fully developed mixed convection flows, with significant viscous dissipation, in a vertical channel bounded by isothermal plane walls having the same temperature and subject to pressure gradient is investigated. It is shown that one of the dual solutions is always unstable and that both are unstable when the total flow rate is big enough. The completely passive natural convection f...

A direct numerical simulation of a turbulent channel flow is performed. The unsteady Navier-Stokes equations are solved numerically at a Reynolds number of 3300, based on thc mean centreline velocity and channel half-width, with about 4 x los grid points (192 x 129 x 160 in 2, y, 2). All essential turbulence scales are resolved on the computational grid and no subgrid model is used. A large num...
