A series of numerical simulations of the dynamo process operating inside gas giant planets has been performed. We use an anelastic, fully nonlinear, three-dimensional, benchmarked MHD code to evolve the flow, entropy and magnetic field. Our models take into account the varying electrical conductivity, high in the ionised metallic hydrogen region, low in the molecular outer region. Our suite of ...

Lattice Boltzmann (LB) method for atmospheric dynamics is developed by considering the characteristics of anelastic approximation. After introducing reference base state values in flows, an LB model, with external force term, has been constructed framework. In proposed mass and momentum conservation equations are solved a regularization procedure, temperature field or scalar transport simulated...

Abstract We study by direct numerical simulation the Rayleigh-Benard convection in supercritical 3He using an anelastic approximation. The latter is based on scaling analysis associated with asymptotic expansions of full governing equations which has important consequence for integration model. approximate are supplemented a parametric state equation and solved numerically finite difference met...
