Prof Ravi Jagadeeshan - Researcher Profile

Biography

Several systems such as granular materials, colloidal suspensions, polymeric liquids, and biological matter, are classified as complex fluids because their microstructure crucially influences their material properties. These systems are inspiring several new technologies. A key challenge is to describe their flow behaviour by understanding the connections between their microscopic structure and macroscopic properties. Ravi Jagadeeshan's research is focussed on developing a theoretical description of the complex flow of polymer solutions. Molecular models and a continuum level description are used in his group to advance the microscopic and the macroscopic description of complex fluid dynamics. The primary aim of the research is to gain fundamental insight into the computational modelling of complex fluid flow by using a multiscale approach that combines insight at the microscopic scale with advanced numerical techniques on a macroscopic scale.
