This review presents when and how extended surface with heat exchanger have been used over the last 15 years in the field of heat transfer. They have been used in this field over a century, but their utilization increases more recent. For past 1 decade, most of the industries required high...

The paper extends object-oriented modelling (OOM) to physical systems including distributed parameter components. An approach is proposed where the basic paradigms of OOM (e.g. encapsulation, independence of module interface from internal behaviour, non-causal model format) are ensured. The...

The performance characteristics of a solar heater and heat exchangers can be effectively improved by using artificial roughness in different forms, shapes and sizes. Artificial roughness is provided in the form of different geometries such as ribs, dimple shape roughness, wire mesh, baffles,...

This paper presents some such case studies for co-and tri-generating various cold and hot utilities using innovative designs of Matrix and Tube-Tube Heat Exchangers and Multi-Utility Heat Pumps developed at Heat Pump Laboratory in IIT Bombay (HPL_IITB). Techno-economic benefits of some of these...

The purpose of this review summarizes the important published articles on the enhancement of the convection heat transfer in heat exchangers using nanofluids on two topics. The first section focuses on presenting the theoretical and experimental results for the effective thermal conductivity,...

The search for new energy sources has a fundamental importance concerning better quality of life for the mankind. Looking for a substitute for the existing pollutant fueled heating equipment, the Hydrogen Group of the Federal University of Paraı́ba (Brazil), has studied the application of...

This paper considers that the case for using electrohydrodynamic (EHD) enhancement of heat transfer has been established, especially in thermodynamic renewable energy applications where temperature levels are relatively low. It goes on to establish the basis on which nucleate boiling heat...

The paper deals with the robustness of fuzzy control. The complementary sensitivity function which in the case of the cancellation control corresponds to the desired closed-loop transfer function must be shaped in order to fulfil the basic equation of robust stability. With classical robust...
