John Craske is a Research Fellow in the Fluid Mechanics Section of the Department of Civil and Environmental Engineering. He has a first-class degree in Architecture from the Bartlett at University College London and in Civil and Environmental Engineering from Imperial College London, where he subsequently completed a PhD thesis on the topic of unsteady turbulent jets and plumes. He is an active member of the undergraduate teaching team in the Department and an associate member of the Institute of Mathematics and its Applications.
Alongside work on unsteady jets and plumes, dispersion and turbulent entrainment, John is currently investigating inverse problems in architectural fluid mechanics. This involves using adjoint sensitivity analysis to quantify uncertainty and to determine the optimal control or design of natural ventilation systems. The methods and theory he develops are relevant to a wide range of environmental fluid mechanics problems involving mixing and contaminant transport. He also studies non-Boussinesq turbulent plumes to model fires.
John investigates the fundamental physics behind practical engineering problems by performing direct numerical simulations and developing accurate, robust and succinct mathematical models. He is interested in design, building physics and systems, applied mathematics and modelling, self-similarity, mixing and flow energetics.
