1. On CFD-Analysis of Heat Transfer of a Heavy-Duty Diesel Engine
Abstract : In this work, a heavy-duty diesel engine was studied by employing CFD simulations on a closed volume engine segment. These simulations were used to evaluate both the effects from certain parameters on the wall heat transfer, and to examine how reduction of heat transfer would effect the engine performance and emission levels.

2. Estimation of Thermal and Hydraulic Characteristics of Compact Brazed Plate Heat Exchangers
Abstract : This thesis work presents various performance estimation methods of compact brazed plate heat exchangers (BPHE) operating in single phase, condenser, evaporator, cascaded and transcritical applications. Such methods play a vital role in development of heat exchanger selection software and during geometry parameter estimation in the new product development process. READ MORE

4. On the numerical modelling of impinging jets heat transfer
Abstract : This thesis collects two studies on heat transfer in impinging jets and on methods for modeling flows of this kind using CFD. Stationary impinging jets with different nozzle to wall distances (z/D = 2 and 6) and Re (10000, 20000, 23000, 30000) are modeled. Steady-state models capture the important features of heat transfer in these jets. READ MORE

5. Combustion Bowl Heat Transfer Analysis in Diesel and PPC Engines
Abstract : This thesis concerns a numerical investigation on heat transfer in internal combustion engines, with the aim of increasing engine efficiency. The efficiency gains are to be extracted from reduced heat transfer losses, by increasing the knowledge on how the heat transfer process is affected by various hardware and operational parameters in the engine.
