Effect of inter-stage pressure on the performance of a two stage refrigeration cycle using inter cooler is studied based on thermodynamic modelling. Six common refrigerants are selected for the analyses. These are R134a, ...

This paper analytically investigates and compares the performance of a proposed ‘all-natural’ NH3/CO2 cascaded booster system to a conventional R404A direct expansion system as well as to an ‘all-CO2’ system with multi-ejector ...

This paper analyzes trans-critical CO2 refrigeration system in typical Indian conditions and the challenges associated with it. A mathematical model for air cooled finned tube gas cooler is developed, validated and used ...

Carbon dioxide (CO2 or R744) and HFO-1234ze(E) are two promising alternatives to the currently employed high-GWP working fluids for food retail applications. In this paper, two indirect refrigeration systems using respectively ...

Predicted scarcity of conventional fuels and their increasing cost have given rise to interest in alternative fuels like biofuels, ethyl alcohol, methyl alcohol, hydrogen, producer gas, acetylene etc. in order to meet the ...

Surface roughness is one of the significant index to measure the product quality of the machined parts. The objective of this work is to contribute towards the development of prediction models for surface roughness. In ...

Sustainable supply chain (SSC) is an emerging research area that focuses on the triple bottom line pertaining to all stakeholders and related activities. Important Business decisions relevant processes, and activities are ...

The Indian food supply chain is highly complex, involving government and private traders, big and small players, traditional as well as modern systems. All parts of the Indian food supply chain—procurement, storage, ...

The fibre of engineering education has evolved from knowledge to competencies. This is a logical consequence of the technologically advanced and multifaceted learning environment where engineers are expected to be technically ...

The growing demand to reduce the environmental burden has encouraged manufacturers as well as users to pursue various green machining strategies and technologies that enable increasingly efficient use of limited resources. ...
