Numerical Analysis of Film Cooling Shield Formed by Confined Jet Discharging on a Flat Plate
(International Information and Engineering Technology Association, 2019)The effects of centrifugal force and thermal conductivity on the effectiveness of a film cooling shield are investigated in this study. A confined jet with 90 degree angle is used, to inject cooling fluid into hot steam, ... -
Numerical and sensitivity analyses of various design parameters to maximize performance of a Vortex Tube
(Elsevier, 2022)In this study, a series of numerical simulations are performed to investigate the performance of a vortex tube (VT) with various design parameters. The study focuses on six design parameters, mainly, inlet pressure, VT ... -
A Numerical Investigation of the Buckling of Doubly Clamped Nano-Actuators Governed by an Integro-Differential Equation
(Springer, 2022)In this article, a fixed point iterative scheme involving Green's function is applied to reach a solution for the buckling of nano-actuators under nonlinear forces. Our solution is convergent. The nano-actuators problem ... -
Numerical Modeling of Nanoparticle-Assisted Laser Thermal Ablation of Tumors
(2021-12)The field of thermal ablation of cancer is growing rapidly in the technical and clinical sectors. Image-guided non-invasive techniques in particular have shown high potential for cancer therapy. Many types of cancer are ... -
Numerical Modeling of Sequential Segmentation for Enhancement of Mixing Inside Microchannels
(2019-12)Microfluidics appeared recently as a new tool that facilitates many applications including chemical synthesis, electronics cooling and biological assays. However, flow on the microscale is characterized by laminar flow ... -
Numerical modelling of hyperbolic phase change problems: Application to continuous casting
(Elsevier, 2023-03)Heat diffusion processes are generally modeled based on Fourier’s law to estimate how the temperature propagates inside a body. This type of modeling leads to a parabolic partial differential equation, which predicts an ... -
Numerical Simulation of the Flow in the Direct Contact Membrane Distillation Flow
(2014-11)Direct Contact Membrane Distillation (DCMD) is modeled using conjugate heat transfer Navies-stokes flow model. A uniform salty and relatively hot feed and colder fresh permeate flow driven by peristaltic pump are considered ... -
Numerical Simulation of Vapor Flow and Pressure Drop across the Demister of MSF Desalination Plant
(Elsevier, 2012-03)This paper presents a numerical simulation of the water vapor flow in an MSF flash chamber along with the pressure drop across the demister. The demister is a simple porous blanket of metal wires mesh (usually made of ... -
Numerical simulations for the optimization of online wash systems for gas turbines
(2011-05)During gas turbine operation, large amounts of small particles are ingested along with the air inflow. As a result, the blade shape changes over time, hence affecting the air flow pattern and reducing efficiency. Field ... -
Numerical Simulations of Drag-Reducing Devices for Ground Vehicles
(2013-01)The aim of the present study is to reduce the aerodynamic drag coefficient of ground vehicles. With the application of efficient drag reducing devices, aerodynamic drag is significantly reduced. This study analyzes numerically ... -
Numerical Study of Localization Failure in Structural Steel Under Impact Loading
(2011-10)High quality steels are used as a skeleton supporting many infrastructure constructions like, for example, skyscrapers, arenas, stadiums, bridges and others. The likelihood that these structures could be severely damaged ... -
Nutrient Recovery from Wastewater Using Desalination Reject Brine
(2020-11)Reject brine, a waste by-product generated during the desalination process, is harmful when discharged into the environment, but it contains some useful minerals such as magnesium. Also, wastewater treatment plants utilizing ... -
Objectively quantified physical activity and sedentary behaviour in a young UAE population
(BMJ Publishing Group, 2021)Objectives There is a lack of public awareness of the importance of engaging in physical activity (PA) in the United Arab Emirates (UAE). Nearly 58% of the UAE adult population self-reports as being physically inactive ... -
Ocean Thermal Energy Conversion (OTEC)
(2015-02-01)Depletion of fossil fuels and gasoline, and their effect on the global climate, necessitate the need for an alternative source of energy. Approximately 170,000 TW of solar radiation fall on the earth’s surface and is not ... -
Offshore Wind Farms
(2016-11)Reliance on non-renewable resources will cause major economic and environmental damage. Comparing with onshore wind farms, offshore winds tend to flow at higher speeds than onshore winds, and thus it allows turbines to ... -
Oil and Water Separation Technique: An Application of Ultrasonic Vibration Technology
(2016-11)Currently there are multiple techniques that are used to separate and purify oil water, these two techniques are quite able to reach high product purities making the a viable component of a burgeoning refinery plant however ... -
Oil Removal From Produced Water Using Natural Materials
(2014-06)The oil and gas industry has had to deal with a massive amount of waste water as a bi-product of the exploration of oil and gas. This waste water referred to as produced water (PW) and the amount of PW increases with the ... -
