2. 1. Performance of Compact Heat Exchanger in Non-Perpendicular Cooling Airflows

   Author : Lisa Henriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulations; Angled; Experiments; Inclined; Heat transfer; Pressure drop; CFD; Heat exchanger;

   Abstract : 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. READ MORE

4. 2. Physical load in computerized office work : with special reference to work tasks and equipment

   Author : Elisabeth Fernström; KTH; []
   Keywords : ;

   Abstract : The main purpose of the studies presented in this thesis wasto measure and quantify shoulder load in computerised officework. Shoulder load was studied during a whole working day andin different work tasks. Shoulder and arm load during keyboardwork and with different modes of physical computer interactionwas also studied.

6. 4. Measurement and evaluation of near-field spray kinematics for nozzles with asymmetrical inlet geometries

   Author : Mohammad Nikouei; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nozzle Geometry; Spray Dynamics; Spray Velocity; Diesel Spray; Ballistic Imaging;

   Abstract : In diesel engines, fuel injection parameters have a commanding effect on mixing and combustion quality. This research aims to enhance the fundamental knowledge of fuel sprays and their primary break-up. In addition, this research provides statistical data to validate simulation models and improve the prediction accuracy in mixing and combustion. READ MORE
