Abstract

Shapes and dynamics of floating droplets under the action of an inclined temperature gradient in the presence of two-dimensional spatial modulation of the vertical component of the temperature gradient are investigated. The case when the vertical component of the temperature gradient is directed downwards is considered. The problem has been studied numerically by the finite difference method. The precursor model has been considered. It is shown that the shape of the droplet is strongly influenced by the thermocapillary stresses caused by a non-uniform substrate heating and the gravity force.

期刊介绍： Microgravity Science and Technology – An International Journal for Microgravity and Space Exploration Related Research is a is a peer-reviewed scientific journal concerned with all topics, experimental as well as theoretical, related to research carried out under conditions of altered gravity. Microgravity Science and Technology publishes papers dealing with studies performed on and prepared for platforms that provide real microgravity conditions (such as drop towers, parabolic flights, sounding rockets, reentry capsules and orbiting platforms), and on ground-based facilities aiming to simulate microgravity conditions on earth (such as levitrons, clinostats, random positioning machines, bed rest facilities, and micro-scale or neutral buoyancy facilities) or providing artificial gravity conditions (such as centrifuges). Data from preparatory tests, hardware and instrumentation developments, lessons learnt as well as theoretical gravity-related considerations are welcome. Included science disciplines with gravity-related topics are: − materials science − fluid mechanics − process engineering − physics − chemistry − heat and mass transfer − gravitational biology − radiation biology − exobiology and astrobiology − human physiology
