2. 41. Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies

   Author : Eva Olsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Gaser; fluid dynamics; plasmas; Gases; RSM; CFD; inverse heat transfer; jet impingement heat transfer; infrared heating; termodynamik; Food and drink technology; Livsmedelsteknik; PIV; SST; food; cylinder;

   Abstract : 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. READ MORE

4. 42. Turbulence Descriptors in Arterial Flows : Patient-Specific Computational Hemodynamics

   Author : Magnus Andersson; Matts Karlsson; Jonas Lantz; Tino Ebbers; Kristian Valen-Sendstad; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : At this very moment, there are literally millions of people who suffer from various types of cardiovascular diseases (CVDs), many of whom will experience reduced quality of life or premature lift expectancy. The detailed underlying pathogenic processes behind many of these disorders are not well understood, but were abnormal dynamics of the blood flow (hemodynamics) are believed to play an important role, especially atypical flow-mediated frictional forces on the intraluminal wall (i.

5. 43. Fluid Dynamics and Granular Growth in High Shear Wet Granulation

   Author : Anders Darelius; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coalescence kernel; Frictional Stress Models; Laser Doppler Anemometry; Population balances; CFD; EFD; High shear granulation; High speed imaging; Multi-dimensional; Multiphase flows;

   Abstract : High shear wet granulation is a key step in the manufacturing of tablets in the pharmaceutical industry. From the pharmaceutical industry’s point of view, there is a desire for predictive quantitative process models to be able to make in-silico process and scale-up simulations, which would shorten and reduce the cost of technology transfer from laboratory scale to manufacturing scale in drug development.

6. 44. A Detailed Kinetic Model for Calculation of the Soot Particle Size Distribution Function

   Author : Fikret Saric; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gaser; fluiddynamik; plasma; Motors and propulsion systems; Motorer; framdrivningssystem; plasmas; fluid dynamics; Gases; Fysik; Physics; Computational Fluid Dynamics; Sectional Method; Method of Moments; Diesel Like Engine Condition; Distribution Function; Detailed Kinetic Soot Model; Soot Particle Size;

   Abstract : The soot particle size distribution was studied via numerical simulation under diesel like engine conditions using a detailed kinetic soot model. Two different mathematical methods of the soot model description have been used in this work. In the first part of the work, the method of moments is presented. READ MORE

7. 45. Mathematical Modeling of Turbulent Reactive Flows

   Author : Mikael Mortensen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PMF; CFD; probability density function; chemical reactions; presumed mapping function; PDF; conditional moment closure; turbulent mixing; computational fluid dynamics; CMC;

   Abstract : The purpose of this thesis has been to study and develop mathematical models of non-premixed turbulent reacting flows. The models developed can be used both by the chemical process industry and for turbulent combustion applications. Furthermore, the models are general and not developed for any specific chemical or mechanical system. READ MORE
