    Computational Fluid Dynamics Study of C-130 External Aerodynamics Flow Field
    To perform CFD investigative study with MINDEF-USAFA-RSAF for the external aerodynamic flow field in the vicinity of a military cargo airplane (e.g. C130H) during airdrop of supplies and hardware in order to assess aerodynamic interference effects on the trajectories of the airdrop. We apply 6 degree of motion freedom to the extraction parachute/cargo pallet to determine the actual trajectory rather than specifying the motion.

    Improvement of BEM Analysis to Incorporate Stall Delay Effect of NREL phase VI Turbine
    We developed hybrid wake modelling by coupling BEM and RANS for near wake regions and LES for far wake regions. Detached Eddy Simulation is used to couple between RANS and DES. BEM method computes the aerodynamic properties of the aerofoil sections along the blade span. A new BEM model with the local radius effect for aerofoil characteristics (other than as a function of Reynolds number and angle of attack only) is proposed. Implementation of the new model showed a good agreement with aerofoil characteristics distribution along the blade span. MATLAB code was developed for both BEM and Inverse BEM analysis.

    CFD (Computational Fluid Dynamics) Study of Ship-to-Bank Interaction
    Ship-to-bank interaction is a complex physical phenomenon that involves not only in the asymmetric pressure field near banks or channels but also shallow water effect. Traditionally many experimental studies were carried out in this field. As numerical method is getting popular, there were various computational approaches as well. In this study, flow around a container ship in confined water is investigated with the open source CFD toolbox, OpenFOAM. Computations with several bank arrangements and different settings are performed. The OpenFOAM results are also compared to experiment results for validation.

    Cancer-detecting Bra
    Dense breast tissue presents a higher risk of breast cancer developing than breast tissue with low density. This denser tissue is related to higher rates of false positive and false negative results from mammography or ultrasound, leading to unnecessary breast biopsy surgeries or failure to detect abnormal tissue. This project with Cyrcadia Health, Inc. developed an original device that has achieved FDA 510K clearance with 650 patients and the on-going final 173 BI-RADS 4/5 patient trail at JamesCare Comprehensive Breast Center in Ohio State University and The El Camino Hospital in Silicon Valley is positively tested and is being commercialized for product release in 2016.

    The Effects of Atmosphere-Ocean-Wave Coupling during Tropical Cyclone for Applications towards Offshore Structures
    Current atmospheric models are unable to produce high winds speeds during extreme events like hurricanes with the existing air-sea flux parameterisation. The Effects of Atmosphere-Ocean-Wave Coupling during Tropical Cyclone for Applications towards Offshore Structures Current atmospheric models are unable to produce high winds speeds during extreme events like hurricanes with the existing air-sea flux parameterisation. One of major limitation of the flux parameterisation is their limited validity at higher wind speeds, due to the lack of observation data in extreme conditions. In recent years, tremendous effort has been put in improving the skill of atmosphere models at higher wind speeds, where coupled models have been found to be able to improve the model results. In such coupled models, the atmosphere models are run together with a wave model or an ocean model or both wave and ocean model. Such model coupling has shown that the ratio of coefficient of enthalpy to coefficient of drag controls the maximum wind speed. As the traditional parameterisation are merely extrapolated beyond their range of validity, they result in too low value of ratio at higher wind speeds. Ocean waves are generated by the transfer of momentum flux on the ocean surface by the winds aloft, while at the same time, the generated waves apply drag on the air flow. Therefore, it has been argued that the coefficient of drag over the ocean surface should also depend on the wave state. From above argument, it can be easily inferred that some combination of higher coefficient of enthalpy and lower coefficient of drag will result in suitable value of ratio.

    Non-invasive/Minimally Contact based Diagnosis of Carotid Artery Disease using Thermal Sensing/Imaging
    We aim to perform in-depth study of vital health sign related to cardiovascular activities to be sensed and quantified with the application of a non-invasive and minimal contact based method. This new technology is to find a method to diagnose coronary diseases, stenosis and blockages through thermal heat transfer performance of the skin above the carotid artery on the neck of human subjects (as a probable region of measurement) using an IR temperature sensor. This work represents a very challenging research that requires detailed analysis of complex biothermal-fluids physiology in order to be modelled accurately the transient phenomena in time.
