Minimum entropy generation (MEG) temperature profiles are derived for steady conduction in a plane wall, a hollow cylinder and a hollow sphere and compared with the classical results. Cases of constant thermal conductivity, temperature dependent and location dependent thermal conductivities for...

An analytical solution is presented to describe the performance of a straight convecting fin operating in an oscillating temperature environment. The solution involves the amplitude parameter, A, and the frequency parameter, B, in addition to the steady-state convection-conduction parameter, N....

This paper describes the results of an experimental study of the inward freezing of water in tubes of circular and square geometries. The temperature-time history is recorded using thermocouples, from which the progress of the freezing front is deduced. The results obtained pertain to the...

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...

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...

EFB (Empty fruit bunch) is among the palm oil biomass residues that have been identified as the most abundant bioenergy resources in Southeast Asia. EFB has a good potential to meet the targeted share of renewable energy in this region. This work presents robust LP (linear programming) model to...
