The comparison between incompressible and compressible flow for aerodynamic coefficients and flow characteristics has been made for NACA 2412 airfoil. The FEM is used to obtain results. The fluid domain of 10C has been constructed to initialize the boundary conditions of incompressible and compressible flow conditions. The structured mesh has been

Objective: To determine the effect of caries towards colonization of Candida spp. Methods: To assess the colonization of Candida spp. in the oral cavity of paediatric patient, samples were obtained from 30 subjects aged five to six years old from International Islamic University Malaysia (IIUM) Dental Clinic and Adik Arif Kindergarten in Kuantan, P

In this experimental investigation, the work reported is about the influence of control on the flow field in the suddenly expanded duct at low supersonic Mach number. A Convergent-divergent (CD) nozzle was designed and fabricated out of brass material assembled with the suddenly expanded duct which was also made of brass material. At the re-circula

Since humans evolutionally adapt to a bipedal gait, the foot is important to allow humans to stand up, walk, run, and to jump. Without the soft tissues and bones at the foot and ankle, our lower limbs could not support the weight of the body. Crush injury of the foot and ankle is a consequence of high energy trauma leading to combined bone and soft

Contamination obsession is the commonest subtype of obsessivecompulsive disorder (OCD), and has been found to be higher among Muslim populations. The presentation of clinical OCD is influenced by one’s religious belief, practice, and culture. Islamic rituals that emphasise on cleanliness or ritual purity could explain why the common contents of o

In this paper, Computational fluid dynamics method is used to simulate the supersonic flow. Convergent-divergent (C-D) nozzle have been used with sudden expansion. The base pressure controlled by using the microjets of 1 mm of orifice diameter is arranged at ninety degrees at PCD 13 mm. The Mach number is 1.87, and the area ratio of 3.24 was consid

Air quality control is very crucial as poor air quality can lead to chronic respiratory organ diseases. Hence, detection of numerous toxic and hazardous gas is utmost significance. A low cost and high sensitivity gas sensor is crucial to monitor the excessive presence of the dangerous gas that can harm human’s health. In recent years, various typ

The purpose of this paper is to provide a conceptual business solution for courier services. This paper will also contribute to the courier service market and transporter market. The application, Run&Roll, will be based on an on-demand delivery service that targets to make on-demand delivery services a norm in Malaysia and eventually throughout

This paper presents an experimental study of suddenly expanded flows at supersonic speed is performed. A Convergent-divergent (C-D) nozzle is used with suddenly expanded duct. At the recirculation zone, the pressure is controlled by using four microjets of 1 mm diameter arranged at PCD of 1.3 as an active control mechanism to regulate the pressure

Computational Fluid Dynamics simulations were carried out using ANSYS FLUENT for suddenly expanded flow through the convergent-divergent nozzle and a suddenly expanded duct. The Length-to-Diameter ratio of 10 for the duct was used in the analysis. Also, an Area Ratio between CD Nozzle exit area and Duct Area was used to be 1.6. The effects of Nozzl
