a nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. the enhancement depends on several factors such as particle shape, particle size distribution, volume fraction of nanoparticles, temperature, ph, and thermal conduc...

In the this research, the hydrocarbon generation potential of the Gadvan Formation as a probable source rock was investigated in the central part of the Persian Gulf at the borders of Iran. Type and maturity level of kerogen were investigated in six wells using the results of Rock-Eval pyrolysis and compared with results yielded by the modelling software program known as Pars Basin Modeler (PBM...

The personalised conditioning system (PCS) is widely studied. Potentially, it is able to reduce energy consumption while securing occupants' thermal comfort requirements. It has been suggested that automatic optimised operation schemes for PCS should be introduced to avoid energy wastage and discomfort caused by inappropriate operation. In certain automatic operation schemes, personalised therm...

Laboratory measurements on dynamic thermal performance of a thermal bridge at the Division of Building Technology, Kungliga Tekniska Högskolan in Stockholm, are presented in this paper. In order to analyse the measured results, dynamic multi-dimensional modelling that can describe the dynamic behaviour of thermal bridges in a simple and accurate way is required. A network method with a Π-link r...

Purpose: The development of precision machine tools requires modelling, simulation and optimization, especially the accurate modelling of machine tool thermal behaviour aimed at improving the machine tool design. Design/methodology/approach: This paper discusses machine tool design improvement based on thermal behaviour modelling and the complexities involved. A highly accurate thermal model of...
