  1. 16. Modelling a Solar Driven Absorption Heat Pump

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Pierre-Antoine Gigos; [2016]
    Keywords : Absorption Heat Pump; Solar Cooling; EES Model;

    Abstract : Absorption Heat Pumps (AHP) have been developed since the late 19th century. They enable to produce cooling and heating directly from a heat source, unlike Compression Heat Pumps that require mechanical work. READ MORE

  3. 17. Modeling and Estimation of Long Route EGR Mass Flow in a Turbocharged Gasoline Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Klasén; [2016]
    Keywords : Long Route Low Pressure LR LP EGR SI Gasoline Spark Ignited Engines Modeling Modelling Mass Flow Estimation;

    Abstract : Due to the continuous work in the automobile industry to reduce the environmental impact, reduce fuel consumption and increase efficiency, new technologies need to be developed and implemented in vehicles. For spark ignited engines, one technology that has received more attention in recent years is long route Exhaust Gas Recirculation (EGR), which means that exhaust gases after the turbine are transported back to the volume before the compressor in the air intake system of the engine.

  4. 18. Simulation of thermal tests in the climatic wind tunnel CD7 at Scania Master thesis project in fluid mechanics

    University essay from KTH/Mekanik

    Author : Jonathan de Laval; [2016]
    Keywords : ;

    Abstract : The Swedish truck and bus manufacturer Scania has a number of test facilities to support the R&D department and for verification of vehicle properties. The latest addition is the climatic wind tunnel Chassis Dynamometer 7 (CD7) which can fit trucks and buses for full scale testing and maintain temperatures in the range from -35 to 50 degree Celsius in the flow circuit, furthermore it can generate both rain and snow conditions.

  5. 19. Modeling, Simulation and Control of Long and Short Route EGR in SI Engines

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Junting Qiu; [2015]
    Keywords : Mean value engine modeling; EGR; long route; short route; residual gas fraction; PID;

    Abstract : Modern engines are faced with increasingly stringent requirements for reduced fuel consumptionand lower emissions. A technique which can partly be used to reduce emissionsof nitrogen oxides is recirculation of combusted gases (Exhaust Gas Recirculation, EGR). READ MORE

  6. 20. Simulation and Optimization of an Air Pollution Control System Dealing with Flue Gases from Combustion of Syngas Produced through a Municipal Solid Waste Plasma Gasification and Melting Process.

    University essay from KTH/Energi- och ugnsteknik

    Author : Minna Laaksonen; [2012]
    Keywords : ;

    Abstract : The aim of this report is to study a proposed air pollution control (APC) system designed to treat flue gases produced during the combustion of waste derived syngas. In order to achieve this objective, a literature study was done to gain insight into the pollution formation during gasification and combustion of syngas, and a model of the APC system was built using the Aspen Plus software.
