This study investigates the effect of ambient oxygen concentration on biodiesel and diesel spray combustion under simulated compression-ignition engine conditions in a constant-volume chamber. The apparent heat release rate (AHRR) is calculated based on the measured pressure. High-speed imaging...

The recent development to control the emissions of large diesel engines has provided opportunities for heat-driven cooling methods in vehicles. An adsorption air conditioning system is therefore proposed in this work for heavy-duty truck application. This system is powered by engine waste heat...

This paper presents measurements of the soot temperature and KL factor for biodiesel and diesel combustion in a constant volume chamber using a two-color technique. This technique uses a high-speed camera coupled with two narrowband filters (550nm and 650nm, 10nm FWHM). After calibration,...

This paper establishes the performance characteristics of convective–radiative longitudinal fins of rectangular, trapezoidal and concave parabolic profiles with simultaneous variation of thermal conductivity, heat transfer coefficient and surface emissivity with temperature. The convection and...

Empirical research on the sources of stress among US medical doctors is scarce. Most research studies reported in leading journals were done on doctors from other countries. The present study explored the sources of stress among American medical doctors. Six factors, workload, work environment,...

Purpose – The purpose of this paper is to investigate the relationship between factors that influence conducting business and the inflow of foreign direct investment (FDI) to Sub‐Saharan African (SSA) and Asian countries. Design/methodology/approach – The factors of business climate...

Performance of biodiesel in engines is well established and biodiesel is currently adjudged as a low carbon fuel with the most potential of replacing fossil fuels. The fossil fuel sources are dwindling in Pakistan resulting in importation of about 8.1 million tonnes at approximately US$ 9.4...
