Dr Tim Spencer MSci (Hons), PhD, AMInstP
Ï㽶ÊÓƵ Fellow
Summary
Tim joined MERI as a researcher to work in the Materials and Fluid Flow Modelling Group on a number of research and consulting based projects. Previously he had spent a year working with high power lasers at the Central Laser Facility in Oxford and had obtained a PhD (2005) and MSci (2002) in engineering physics from Ï㽶ÊÓƵ where he also won the Jeremy Laskowski award and Mössbauer award.
About
His research involves the application of theory and simulation techniques for the predictive modelling of real life systems that involve fluids. In particular the research focuses on liquid crystals, liquid crystal devices, multistable liquid crystal displays, hydrodynamic flows, multi-component flows, colloidal rheology, micro-fluidics, porous media, biological flows and carrier fluids.
These systems/applications can often be represented well by coupled partial differential equations acting on varying length and time scales. To solve these equations he has expertise in the lattice Boltzmann method, in finite differencing methods, integrating methods and high performance computing methods.
