We describe the theory and implementation of a three-dimensional fluid dynamics code which we have developed for calculating the surface geometry and circulation currents in the secondaries of interacting binary systems. The main method is based on an Eulerian-Lagrangian scheme to solve the advective and force terms in Euler’s equation. Surface normalised spherical polar coordinates are used to...

Refrigeration cogeneration systems which generate power alongside with cooling improve energy utilization significantly, because such systems offer a more reasonable arrangement of energy and exergy ‘‘flows’’ within the system, which results in lower fuel consumption as compared to the separate generation of power and cooling or heating. This paper proposes several novel systems of that type, b...

Spinodal decomposition of highly viscous binary mixtures near the critical composition is well described by the Cahn-Hilliard equation. In this short communication we present a model that introduces the thermal effects due to the presence of a solid structure immersed in a phase-separating mixture. The presence of solid boundaries is taken into account by means of a volume-penalisation method b...
