Research interests
Computational Fluid Dynamics, Particle Dispersion in Turbulent flows, Numerical Optimization, Lattice Boltzmann Method. GPU based computing using CUDA.
My research interests span from the theoretical and experimental investigations into the fundamental aspects of fluid turbulence and turbulent dispersion to nonlinear dynamics in cavity flows, as well as novel computational methods for fluid flow, including:
- Built environment: modelling turbulent flows and investigating its applications in the built and urban environment. Current research topics include:
- Computational fluid dynamics (CFD) modelling of hospital indoor air quality including airborne infection risk.
-CFD-based multi-objective optimisation of hospital ward design to mitigate infection risk while maintaining occupant comfort.
-CFD-based modelling and optimisation in-duct UVC sterilisation systems for healthcare environments.
-Novel sensor supported simulation-based predictive control indoor environment including controlling airborne contamination in hospital wards.
- Multiscale modelling: developing in-house massively parallel GPU-based simulation tools for single and multi-phase fluid modelling for engineering problems. Current projects:
- Novel real-time Lattice Boltzmann (LB) simulation of urban heat and pollution modelling;
- Multiscale LB modelling of coupled hydro- and morphodynamics in environmental flows with applications to land and marine use management and geohazard prediction and mitigation.
- Multiphase flow and heat transfer: including flow in anaerobic digesters (AD) in wastewater treatment plants, ground-source heat exchanger technology, flow and heat transfer, and phase change materials for thermal performance. Current projects:
- Multiphase flow and heat transfer in cooling systems for electronic circuits, built environment and data centres.
- Novel coaxial heat exchanger technology for ground-source heat pumps
- Novel unified radiation transport and turbulent hydrodynamics solver on massively parallel graphics processing units (GPUs) for solving highly coupled multi-physics problems in nuclear engineering.
- Computational modelling of spray carryover in personal care products.
- Biological/Medical fluid flow: including flow in a human cardiovascualr system and flow in liver. Current projects:
- In-Silico predictions of post-Surgical haemodynamics in individual patients using opensource computatonal fluid dynamics tool OpenFOAM.
- Multiphase tracer kinetic modelling of biological tissue flows with applications in liver surgery.
