This paper presents the Computational Fluid Dynamic (CFD) analysis to study the effect of Mach numbers on velocity distribution at different area ratio and nozzle pressure ratio in the flow field from convergent-divergent nozzles to a suddenly expanded circular duct of larger cross-sectional area. The study is focusing on velocity distribution alon

The tourism sector in Malaysia has undergone substantial growths as a result of the efforts taken by the Ministry of Tourism in policy planning and implementation. It is the government’s long-term goal to make Malaysia as the most popular tourism destination. The growth of tourism sector in Malaysia can be measured by tourist arrivals and receipt

Purpose: The purpose of this paper is to investigate the validation of the ASEAN+3 financial cooperation agreement among its members. In particular, it examines the long- and short-run relationships among the stock market indices of eight countries: China (CH), Japan (JP),Korea (KR), Malaysia (MY), Indonesia (ID), Philippines (PH), Thailand (TH), a

Purpose - This paper aims to highlight on the unique aspects of Islamic microfinance based on the experience of Baitul Maal Wa Tamwil (BMT) in Indonesia. Design/methodology/approach - It adopts the content analysis approach and focuses on three phases of financing, namely, pre-financing, financing and post-financing using coding and model buildings

This study describes a fuzzy controlled hybrid engine powered car. The car is powered by the lithium ion battery capacity of 1000 Wh is charged by the 50 cc hybrid engine and power regenerative mode. The engine is operated with lean mixture at 3000 rpm to charge the battery. The regenerative mode that connects with the engine generates electrical p

The adoption of lithium-ion battery technology for electric vehicles/hybrid electric vehicles (EV/HEV) has recently received attention worldwide. The price of cobalt (Co) and lithium (Li) has increased due to the production of EV/HEV. A used lithium battery is a valuable source of active metals (Co, Li, and Al) and the optimal way of extracting the

Electrical vehicle needs to draw power from battery for acceleration. It needs to draw high current for speeding up to 130 km/h on 0% gradient and 40 km/h on 5-10% gradient. Battery generates powerful electrical currents to meet the power demands of EV, causing significant warming of the Li-ion cells. The battery operating temperature of 40ºC and

Thermoelectric generators are all solid-state devices that convert heat energy into electrical energy. The total energy (fuel) supplied to the engine, approximately 30 to 40% is converted into useful mechanical work; whereas the remaining is expelled to the environment as heat through exhaust gasses and cooling systems, resulting in serious green h

Thermoelectric generator generates electrical power from heat based on the temperature gradient. The total energy (fuel) supplied to the engine, approximately 30 to 40% is converted into useful mechanical work, whereas the remaining is expelled to the environment as heat through exhaust gases and cooling systems, resulting in serious greenhouse gas

Climate change is recognized as one of the greatest environmental threats facing the World today and it has long been appreciated by governments that reducing the impact of the IC engine powered motor vehicle has an important part to play in addressing this threat. This article presents the parametric study of a palladium (Pd)/ graphene oxide (GO)
