RESEARCH STUDENTSHIP ON A TOPIC IN TURBULENCE RESEARCH

A studentship is available immediately for the duration of three years and will pay a maintenance stipend of 9133 pounds sterling per year and full EU/home fees.

The Ph.D. student will have the choice between at least four research topics including (1) laboratory experiments on fractal generated turbulence, (2) dispersion in turbulent flow, (3) mixing by chaotic
advection and vortices and (4) interscale transfer and pressure spectra in turbulent flows using wavelets and direct numerical simulations. This studentship involves a collaboration with the Hong Kong University of Science and Technology which means that the student may spend one or two months per year in Hong Kong.

PhD studentship in Computational Fluid Dynamics

A postgraduate studentship funded by the Natural Environment Research Council is available (for qualified UK residents only) to work on a project concerning the 3D structure of clouds.

At Imperial College (IC), London, we are currently developing a new approach to the solution of the radiative transfer equation in 3D at visible and infrared wavelengths. The model is being applied to problems concerning the scattering of light by inhomogeneous clouds. It is unique in this context and is expected to provide considerable advances in understanding of how clouds affect the Earth's radiation balance. One major problem, however, is the specification of cloud properties as input to the scattering model. Information regarding the distribution of cloud physical, optical and radiative properties is needed to constrain and validate the radiation code. However, complete sets of observations are rare so we are obliged to use theoretical simulations. In this project we will develop and use one of two new approaches to simulating cloud inhomogeneity, one based on the fractal geometry of clouds and its effect on light scattering, the other based on non-eddy-diffusive sub-grid modelling for Large Eddy Simulations which can take into account cloud shape properties below grid resolution.

Candidates should have a first degree (Class 1 or 2.1) in aeronautics, mathematics or physics.
