Abstract
Microgravity conditions pose unique challenges for fluid handling and heat transfer applications. By controlling (curtailing or augmenting) the buoyant and thermocapillary convection, the latter being the dominant convective flow in a microgravity environment, significant advantages can be achieved in space based processing. The control of this surface tension gradient driven flow is sought using a magnetic field, and the effects of these are studied computationally. To capture the deformable interface, a numerical method to solve the Navier–Sokes equations, heat equations and Maxwell’s equations was developed using a hybrid level set/volume-of-fluid technique. The method is tested against both analytical and experimental results and was found to be in good agreement. The method was then implement to solve (a) a stationary ferrofluid droplet under the influence of a magnetic field and (b) a rising and falling magnetic droplet under various conditions. The method is shown to be a viable technique to solve such complex multiphase heat transfer problems.
