Mathias Engh
About
Master of science from the Department of Chemical Engineering at NTNU. The master thesis involved developing a self optimizing numerical resolution with respect to both element size and polynomial expansion (hp-adaptivity) to find the solution of a partial integro-differential equation (the population balance equation) with a spectral element numerical method.
Research interests include reactor modeling for multiphase systems, the population balance equation and the weighted residuals family of numerical methods (orthogonal collocation, least squares).
Teaching or supervising in the following subjects:
TKP4160 - Transport processes
TKP4145 - Reactor technology
TKP4535 (TKP6) - Reactor modeling
