Three-phase flow occurs in petroleum engineering, for example when gas is injected into a reservoir that is past its peak production to recover additional volumes of oil. The gas phase may be carbon dioxide, which has the additional benefit of storing this greenhouse gas underground. Novel descriptions are sought for flow processes on the length scale of meters to kilometres, while incorporating the physical processes occurring on the millimeter scale or smaller (e.g., mobilisation of blobs of oil that have become trapped in the porous reservoir rock). Robust and efficient numerical algorithms, supported by sound mathematical theories and proofs, are of wide importance in all engineering disciplines and in particular in this field for accurate flow predictions.

This prize is equipped with a substantial amount of money from which I can pay a number of Ph.D. students during the next few years. I am now looking for suitable candidates. So if you know good students who are about to finish their Master's studies and who might be interested in doing a Ph.D. on a topic related to my research interests (computer algebra for special function identities and inequalities, symbolic summation and integration, differential and difference equations, Groebner bases, formal power series, and the applications of all this in combinatorics, experimental mathematics, engineering, physics, and so on), then please consider recommending me to them. (Or them to me. Or both ways.)
