Department Name: Wolfson Sch of Mech, Elec & Manufac Eng
Abstract
The proposed research consist of the development of modelling techniques for advanced simulations of physical phenomena taking place in the Earth's Atmosphere. In particular, the research will contribute to the improvement of unstructured meshes based nonhydrostatic models for limited area geophysical flows which can alleviate limitations of regular grids traditionally used for weather forecasts. Main feature of the research will be the multi-scale approach that would encompass a large number of atmospheric phenomena. A particular aspects of new developments will include high performance computing and new algorithmic features aiming at increasing efficiency of numerical simulations.

| Description | A massive parallel code for simulating environmental flows using unstructured meshes has been developed. The code is used for a systematic review of stratified flows past a sphere. Due to the feasibility of non-regular meshes the problem of flow past two spheres has also been tackled. |
| Exploitation Route | The developments of massively-parallel edge-based nonhydrostatic models achieved during my PhD program are relevant and applicable to the scientific communities working on atmosphere/ocean modelling adopting fully unstructured meshes. The possibility of implementing flexible meshes in global weather and climate forecasts, as well as in regional and smaller scale models, opens new perspectives for accurately resolving complex flows pertinent to study of wind energy, convective motions, gravity wave dynamics and orographic flows, micro-meteorology dynamics, and cloud microphysics. Notably, the fully unstructured mesh framework is inherently suited for multiscale processes, e.g. large-scale convection in the tropical region, where the interaction between phenomena at different dynamic scales requires locally high resolution meshes. |
