Mechanical Engineering
We are a team of young researchers working on applied mechanics problems to grasp fundamental insight by employing computational and mathematical techniques. Our research is primarily focused on understanding commonly observed phenomena, such as boiling and churning motion of water in a tea pot, solidification and melting of ice, rising bubbles/falling particles in a beverage bottle, bursting bubbles at sea-air interfaces, and meandering of plumes from a lighted incense stick. Understanding these fundamental mechanics problems have a potential role in explaining reasons for the observed heat and mass transfer rates in boilers/condensers, pattern formation during alloy solidification, cloud formation and storm prediction.
