Sammanfattning : Rapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. LÄS MER
Sammanfattning : A new receiver concept utilizing impinging jet cooling technology has been developed for a small scale solar dish-Brayton system. In a typical impinging receiver design, the jet nozzles are distributed evenly around the cylindrical absorber wall above the solar peak flux region for managing the temperature at an acceptable level.

14. Numerical investigation of the turbulent flow and heat transfer around a heated cube cooled by and impinging jet in a cross-flow
Sammanfattning : Impinging jets are used for many industrial applications where high heat and mass transfer rates are required. The electronic industry is one of the fastest growing industries and applications of cooling technology in this field are of considerable importance. Forced channel flow is frequently used as a cooling technique. LÄS MER
15. Fundamental Experimental and Numerical Investigation Focusing on the Initial Stage of a Top-Blown Converter Process
Sammanfattning : The aim of this thesis work is to increase the knowledge of phenomena taking place during the initial stage in a top blown converter. The work has been done in a few steps resulting in four different supplements. Water model experiments have been carried out using particle image velocimetry (PIV) technology. LÄS MER
