The design of launchpads for space vehicles is of paramount importance to satellite deployment and space exploration. The interaction of exhaust flow and launchpad structure must be understood for reliable designs. We use a shock tube to model this phenomenon at a laboratory scale. In this direction, we have simulated two flow scenarios using computation fluid dynamics techniques to find out how the flow features evolve during this interaction. Through our results, an attempt could be made to find out which flow scenarios impart larger structural loading on the launchpads.
