Interaction of capillary-gravity waves with bubbly turbulent flows

The work will be a mix of computational (CFD) and analytical work with scope of doing experiments at a later stage. The problem to be studied builds upon our recent work on interfacial waves [1,2,3] with the aim of studying wind generation of waves and turbulence in the uppermost layer of the ocean, wave breaking, bubble entrapment and fragmentation, bubble bursting and aerosol spray formation. This is a very large and important problem in oceanic and environmental sciences and engineering. Understanding of problems in these areas will provide important inputs to numerical weather models. The student is expected to be interested in fluid mechanics and computer programming. The computational part of the work on turbulence will be co-supervised with Prof. Partha Goswami and will involve doing Large Eddy Simulations. There will be scope to interact and collaborate with prominent research groups working at ICTS Bengaluru and IIT Madras.
