A. Coherent structures in turbulent convection
Turbulent convection occurs in areas ranging from atmospheres, oceans, mantles to manufacturing processes, electronic cooling, PCR as well as in day to day cooking. The heat flux in turbulent convection is critically decided by the phenomena near the hot surface. Our interest is in understanding the dynamics of the coherent structures near the hot, horizontal surface, observed as rising sheets called line plumes, and their role in transporting heat. A model to explain the observed mean plume spacings  and total length of plumes  have been built. Commonalities in the plume structure under differing conditions were detected, implying a common dynamics. Scaling laws for the dynamics of line plumes have been found recently .
