Abstract

In present work an attempt is made to analyze bullet headed spacecraft fuel tank by using Ansys Fluent 14.5 tank is partially filled with liquid oxygen (Lox). Two fuel tanks with and without baffles considered to study splatter behavior of fuel. The tanks were accelerated to 15 m/s2 in positive X direction for 1 second. From analysis it is found that intensity of sloshing is highly decreased in the fuel tank which is provided with baffles. The effects of baffles on fluid behavior are clearly seen in results drawn. Pressure distribution in both fuel tanks was determined and it is found pressure is less in fuel tank provided with baffles. Further work can be expandable to achieve more stability of fuel tank by varying number, shape and size of baffles.
