Our heartfelt congratulations go to Dr David Chua who has recently been conferred PhD in Hyro-Environmental Engineering. David’s PhD research was on 3D computer modelling of turbulent flow around a bridge structure submerged in a river. Extreme hydrological events have increased the frequency of flooding in recent decades, resulting in bridge failures and their associated damages. Turbulence structures within the flow field are highly energetic and possess high sediment entrainment capacity which will lead to the scour formation around the bridge foundation and consequently causes structural instability or even failure of the structure.

His research employs a computational fluid dynamic (CFD) technique to elucidate the complex flow mechanisms around bridge abutments in changing conditions. The CFD code is used to analyse the effect of bridge abutment length on the turbulence structure and flow field through the bridge opening. The modelling results were interpreted with visualisation techniques which allow the reader to visualise how turbulent structures look like in 3D and what effect these structures have on the river bed at near vicinity to the bridge abutment. The findings attempt to contribute to the design of resilient hydraulic structures especially on considering the shape and size of a bridge foundation.

David’s research required him to learn some programming skills, mainly on Fortran and MATLAB, in addition to the series of computer softwares. Such computer modelling practices needed the use of High Performance Computing (HPC) of up to 1000 CPU cores for months. (To put into perspective, a computer at home only has 8 CPU cores.) Currently, David is working as a senior scientist in the Intertek Energy and Water Consultancy Services, based in Hampshire, UK. Intertek was co-founded by Mr. Thomas Edison in 1896 and is now a testing industry leader with more than 44,000 employees in 1,000 locations in over 100 countries. David’s role in the company involves the modelling of water bodies in rivers, coastal environment and reservoirs. One of the most interesting projects led by David was the adoption of machine learning techniques to predict the algae growth in reservoirs.
