... regression models to predict k_eff under different conditions. Findings Experimental values of k_eff were in the range of 0.090–0.127 W m⁻¹ K⁻¹, typical for biomasses. The results showed that the reduction of the BSG particle...

..., design and optimize the behavior of practical thermal processes and systems. The purpose of this paper is to present modeling at the different length scales and then addresses the question of coupling the different models to obtain the overall model for the system or process. Design/methodology...

...Sailei Zhang; Jeffrey Yanke; David R. Johnson; Matthew J.M. Krane Purpose – A single-domain multi-phase model is developed for macrosegregation and shrinkage pipe formation in castings, as functions of buoyancy- and shrinkage-induced flow. The paper aims to discuss these issues. Design...

...Johnny Chung‐Yin Tsai; Hong G. Im; Taig‐Young Kim; Jaeho Kim Purpose The purpose of this paper is to present a three‐dimensional CFD model that simulates the pyrolysis, combustion and heat transfer phenomena in a refuse‐derived fuel (RDF) gasifier. Correlations between different operation...

...María Cristina Sánchez; J.R. Mahan Purpose The purpose of this paper is to present the results obtained from numerical models of radiant energy exchange in instruments typically used to measure various characteristics of the Earth's ocean‐atmosphere system. Design/methodology/approach...

...Evgeny Shavelzon; Dan Givoli Purpose The interaction of a global model (GM) and a local (regional) model (LM) of heat flow is considered under the framework of so‐called “one‐way nesting”. In this framework, the GM is constructed in a large domain with coarse discretization in space and time...

... verification for macrosegregation simulation. Design/methodology/approach A partial verification of a finite‐volume computational model of macrosegregation in direct chill (DC) casting of binary aluminum alloys, including the coupled transport phenomena of heat transfer, fluid flow and species transport...
