Sammanfattning : Hot air impingement is a special form of forced convection, where the air is focused through the use of nozzles at a surface. In combination with rather high air velocities, a jet like phenomenon can evolve, which when used in for example cooking can achieve high heat transfer capacities. An Impingement oven prototype was constructed. LÄS MER

Sammanfattning : Heat and mass transfer to/from a single active particle in bubbling and circulating fluidized beds have been studied with application to fluidized bed combustion. A method of calculation of the heat and mass transfer coefficients in a bubbling fluidized bed (BFB) has been developed. LÄS MER
4. 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
Sammanfattning : Bubble columns are used in the chemical industry to perform gas liquid reactions, like oxidation, hydrogenation and fermentation. The objective of the present thesis was mainly to study the fluid dynamics of semi batch packed bubble columns at both atmospheric and pressurized conditions. LÄS MER
