4. 2. Estimation of Thermal and Hydraulic Characteristics of Compact Brazed Plate Heat Exchangers

   Author : Vijaya Sekhar Gullapalli; Institutionen för energivetenskaper; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazed plate heat exchangers; CFD; heat transfer; pressure drop; heat exchanger selection software; transcritical-CO2 calculations; heat exchanger rating; evaporation; condensation; refrigerant properties; discretized calculations;

   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

5. 3. Turbulent Forced Convection Air Cooling of Electronics with Heat Sinks Under Flow Bypass Conditions

   Author : Hans Jonsson; KTH; []
   Keywords : forced convection; heat transfer; pressure drop; turbulent; air cooling; bypass; plate; strip; pin; fin; heat sink; electronics; experimental; numerical; CFD; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Air cooling is still the dominant method for dissipating theheat produced by electronic components. In a typical electronicdevice, the components are situated on a Printed Circuit Board(PCB). For most applications natural convection is sufficientto cool the components. READ MORE

6. 4. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables

   Author : Behrouz Nourozi; Sasan Sadrizadeh; Adnan Ploskic; Carey Simonson; KTH; []
