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 ongoing deregulation of electricity industries worldwide is providing incentives for microgrids to use small-scale distributed generation (DG) and combined heat and power (CHP) applications via heat exchangers (HXs) to meet local energy loads. Although the electric-only efficiency of DG is...

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...
