Today, in the 37th ScienceBeer, Ramandeep was our Science Brewer. Ramandeep is a Doctoral Candidate in TU Dresden and works on Fluid Mechanics. The water sources of our planet are getting polluted every day. Rivers are one of the main sources. Due to the flow of the river, the flowting particles can travel longer distances. Today Ramandeep explained how he simulates the river flow and predicts the destination of flowing particles. Similar analysis can be used in many relevant studies. In principle, for any flowing fluid. Thank you Ramandeep.
