16. Flow boiling of ammonia and propane in mini channels
Sammanfattning : The environmental concerns in recent times have grown especially after signing Montreal protocol. In the last ten years, researchers have focussed mainly on understanding the boiling and condensation phenomena of HFC refrigerants in minichannels. LÄS MER
17. Performance of Compact Heat Exchanger in Non-Perpendicular Cooling Airflows
Sammanfattning : During recent years the main focus in the vehicle industry has been on cutting the fuel consumption and emissions as well as improving the vehicle performance. To be able to meet these demands additional systems are being introduced into the vehicle. LÄS MER
18. Extensional rheometry through hyperbolic contraction
Sammanfattning : To understand fluid rheology, properties such as consistency and viscosity are determined in both shear and extensional flow. Many commonly-used materials and formulations exhibit complex rheological properties and in order to determine the behaviour as well as predict and govern their properties, effective and reliable characterisation of these fluids is important.

19. Optimum Design of Heat Exchanger Networks in Retrofit Situations
Sammanfattning : Today, the most important activity in heat exchanger network synthesis is the retrofitting, rather than grass-root design, of networks. There is a vast potential for energy improvement in many processes by increasing the level of internal heat exchange. LÄS MER
20. Catalytic Converters for Automotive Exhaust Applications. Flow Dynamics, Mass Transfer and Optimization
Sammanfattning : In order to reduce emissions from vehicles powered by an internal combustion engine, an exhaust aftertreatment system is normally mounted on the engine. This aftertreatment system normally consists of one or several catalytic converters. LÄS MER
