TITLE: an introduction to molecular modelling of complex fluids in rheology
Abstract:听 听
In this seminar, I will introduce the field of rheology with some fundamental concepts supported by real world examples of complex fluids.听 We will then consider molecular simulation as a tool for conducting microscale experiments on different molecular models of complex fluids. Finally, I will introduce my own modelling approach followed by some results from the past year.

TITLE: free surface flow past a high-speed submerged hydrofoil
Abstract:听 听
In this seminar, I will introduce, in the limit of large Froude number, a closed-form, numerical solution of spectral method for steady, two-dimensional, inviscid, free-surface attached flow over a submerged planar hydrofoil for arbitrary angles of attack and depths of submergence. The doubly connected flow domain is conformally mapped to a concentric annulus in an auxiliary plane. The complex flow potential and its derivative, the complex velocity, are obtained in the auxiliary plane by considering their form at known special points in the flow, and the required conformal mapping is determined by explicit integration. Finally, three real solution parameters of the conformal mapping will be determined as the simultaneous roots of three nonlinear algebraic equations arising from the flow normalization through Newton's iteration. The numerical solution format enables precise evaluation of various flow quantities, including the lift on the foil, in relation to physical parameters.
