The present study investigates the effect of partial surface texturing, containing large number micro-dimples, in lubrication mechanisms. A CFD model is applied to examine influence texturing on pressure and velocity distribution flow between mating surfaces with relative motion or drop. Various parameters were analyzed. results indicate that equivalent volume step effectively simulates for a w...

Li, Yuwei. "Coupled computational fluid dynamics/multibody dynamics method with application to wind turbine simulations." PhD ii To my family iii ACKNOWLEDGMENTS I would like to express my greatest appreciation to my advisor, Associate Professor Pablo M. Carrica, who has been continuously supporting me throughout my Ph.D. research with his knowledge, experience, enthusiasm and patience. I am gr...

This comparative cross-sectional study was conducted in the pediatric daycare unit, Hospital Universiti Sains Malaysia to determine the prevalence of craniofacial deformities (CFD) and the association between these deformities and different clinical presentations among thalassemia patients. Patients were classified as either craniofacial deformity positive (CFD+) or craniofacial deformity negat...

This paper discusses a framework for integrated Augmented Reality (AR) architecture for indoor thermal performance data visualization that utilizes a mobile robot to generate environment maps. It consists of three modules: robot mapping, Computational Fluid Dynamics (CFD) simulation, and AR visualization. The robot mapping module enables the modelling of spatial geometry using a mobile robot. I...

8 High concentrations of airborne particulate matter in factories can cause serious health problems 9 for workers. One significant reason for these high concentrations is the poor performance of the 10 ventilation systems in workplaces. This investigation developed a strategy that combines 11 computational fluid dynamics (CFD) simulations and on-site measurements to study and improve 12 the ven...

Initial results of an ongoing Navier-Stokes Computational Fluid Dynamics study of horizontal axis tidal current turbine hydrodynamics are presented. Part of the underlying motivation is assessing the effects of the Reynolds number on turbine performance and loads in steady and unsteady flow regimes. The study aims at a) providing initial verification and validation of Navier-Stokes CFD for stea...

In forward osmosis (FO), an osmotic pressure gradient generated across a semi-permeable membrane is used to generate water transport from a dilute feed solution into a concentrated draw solution. This principle has shown great promise in the areas of water purification, wastewater treatment, seawater desalination and power generation. To ease optimization and increase understanding of membrane ...
