Passive Control of Base Drag in Compressible Subsonic Flow Using Multiple Cavity
Research Output | Dar Al-hikmah Library | IIUM Only

Compressible flow in a suddenly expanded square duct was investigated experimentally to assess the effectiveness of the passive control in the form of the cavities. The flow parameters studied were the Mach number, nozzle pressure ratio, L/W ratio, and area ratio. The test were conducted for multiple cavities and without multiple cavities. From exp

Flow Control with aero-Spike Behind Bluff Body
Research Output | Dar Al-hikmah Library | IIUM Only

Flow control in high-speed is challenging due to the high-pressure shock and low-pressure recirculation bubble attached around the vehicle. Wave drag, and Base drag are important accouterments of flow around high-speed objects. This paper deals with base drag, only and presents an experimental study of aerospikes behind the base of bluff bodies to

Assessment of Different Turbulence Models in Simulating Axisymmetric Flow in Suddenly Expanded Nozzles
Research Output | Dar Al-hikmah Library | IIUM Only

A numerical simulation was carried out to compare various turbulence models simulating axisymmetric nozzle flow past suddenly ex-panded ducts. The simulations were done for L/D = 10. The convergent-divergent nozzle has been modeled and simulated using the turbu-lence models: The Standard k-ε model, The Standard k-ω model and The SST k-ω model. N

Oral Health Attitudes and Behaviours Among Undergraduate Health Sciences Students
Research Output | Dar Al-hikmah Library | IIUM Only

Oral health is a component of overall health that has an impact on an individual’s general well-being. It is believed that individuals enrolled in undergraduate health sciences are expected to have a positive attitude and behaviour toward their oral health. This study is conducted to investigate and compare the oral health attitudes and behaviour

Using Model Predictive Control in Renewable Energy Sources
Research Output | Dar Al-hikmah Library | IIUM Only

The integration of renewable energy sources (RES) poses challenges due to their intermittent nature and the requirement for grid stability and reliability. This study explores the application of Model Predictive Control (MPC) as an advanced control strategy for effective RES integration. MPC utilizes mathematical models and prediction algorithms to

Cfd Analysis of convergent-Divergent Nozzle Flow and Base Pressure Control Using micro-Jets
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents numerical study was undertaken to identify the use of the micro-jets to regulate the pressure in the region from two-dimensional convergent-divergent (CD) Nozzle. At the exit of the divergent nozzle in the base region 1 mm of two micro-jets orifice diameter has been arranged at ninety degrees at pcd 13 mm to control base pressur

Enhancement of Machining Performance During Electrical Discharge Machining of Stainless Steel with Carbon Nanotube Powder Added Dielectric Fluid
Research Output | Dar Al-hikmah Library | IIUM Only

Electrical discharge machining (EDM) is a nontraditional process of removing material from an electrically conductive work piece. It produces sparks to produce any desired shape cavity or geometry. The demand for good surface finish of a workpiece in EDM has developed a new method to improve surface condition where powder material is added to diele
