1. Drying kinetics, coalescence and agglomeration of dairy products particles
Sammanfattning : Spray drying is used in the food, pharmaceutical, and chemical industries for producing powder from a liquid feed. The unique advantages of spray drying are producing powders of a specific particle size and moisture content, handling heat sensitive products, and high capacity. However, spray drying is a complex process. LÄS MER
2. Numerical analysis of coalescence-induced jumping droplets on superhydrophobic surfaces
Sammanfattning : Bio-inspired superhydrophobic surfaces are used in numerous technological applications due to their self-cleaning ability. One of the several mechanisms reported in literature and responsible for self-cleaning is the phenomenon of coalescence-induced jumping of droplets from such surfaces. LÄS MER
3. Dynamics of Fluid Particles in Turbulent Flows; CFD simulations, Model Development and Phenomenological Studies
Sammanfattning : The thesis investigates the dynamics of fluid particles in turbulent flows, which plays an important role in the chemical, pharmaceutical, food and petroleum industries. Phenomenological studies, new mathematical models for the breakup phenomena, and development of a simulation method for chemical reactors constitute the main parts of this thesis. LÄS MER
4. Droplet growth in atmospheric turbulence : A direct numerical simulation study
Sammanfattning : This Ph.D. thesis examines the challenging problem of how turbulence affects the growth of cloud droplets in warm clouds. Droplets grow by either condensation or collision. LÄS MER
5. Fluid Dynamics in Gas-Liquid Stirred Tank Reactors: Experimental and Theoretical Studies of Bubble Coalescence
Sammanfattning : This work deals with studies of bubble coalescence in turbulent flows of gas-liquid stirred tank reactors. Coalescence plays an important role in determining bubble size distribution, on which flow and mass transfer in such reactors largely depend. LÄS MER
