Computation Fluid Dynamics

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.

This study aims to use CFD analysis of CT scan data from the nasal cavities of a range of older Asian males to investigate the impact of geometric variations between older nasal cavities on the airflow structures and airconditioning capacity of the nasal cavity. Air flow mechanisms, heat transfer rates and humidification efficacy are analysed in order to arrive at a more precise understanding of the role of nasal geometry in the presentation of respiratory ailments.

The main objective of this research is to optimize the design of the Tunnel kiln for efficient fuel usage. To achieve that, the temperature distribution from the simulation needs be matched with the desired Tunnel kiln curve found in industry. This objective can be achieved by CFD simulation where temperature, velocity and emission distributions inside the Tunnel kiln can be obtained. Generated temperature distribution can be matched with the industrial curve and by interpreting the curve, efficient design can be suggested.

The aim of this research is to employ a sensitivity study for the total thrust of a ducted twin counter-rotating propeller system design for UAV applications using computational fluid dynamics (CFD). Two factors were investigated: propeller spacing and difference between blades pitch angle. Using discrete values for both factors, 32 designs were analysed and evaluated. The same approach was also used for an equivalent unducted propeller system to access the influence of the duct.

The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory.

The goal of this study is to demonstrate and quantify the impact that the uncertainty in thermophysical properties has on key metrics of thermal hydraulic importance for MSRs, in particular on the heat transfer coefficient. In order to achieve this, computational fluid dynamics (CFD) simulations using the RANS k-ω SST model were compared to published experiment data on molten salt.
