hela Sverige At Research and Development you will be a key contributor to the next generation outstanding luxury cars from Volvo. Together with other engineers around the world, you and your team will create innovative human-centric car technology that makes life less complicated and more enjoyable for people. Are you interested in design and connected car technology? Do you share our passion for people, the environment and our urge to create a superior driving experience? Research and Development is the place for you to prosper.
This thesis work will be carried out within the Fuel System department, which is a part of VCC 's Research and Development organization.
The department consists of 70 employees, all dedicated to develop a competitive solution for future cars in a stimulating working atmosphere. The fuel system department is responsible for fuel storage, refueling, fuel level indication and delivering fuel to the engine. The department also develops systems driven by legal requirements such as the EVAP and leakage diagnostic systems for hydrocarbon emission control.
Description and Scope
The purpose of this thesis work is to develop a simulation method to investigate and predict the effect of heat on adsorption and desorption of hydrocarbons in a carbon canister. The canister is used to prevent hydrocarbon fuel emissions to leak into the surrounding. Fuel emissions from cars are subject to legal requirements to avoid fuel smell and health related issues with hydrocarbon exposure for humans.
The hydrocarbons is evaporated from the fuel storage tank and is feed through the canister. To prevent hydrocarbon from diffusing through the canister and to the surrounding, the canister must be purged with clean air at certain intervals. The clean air empties the canister and the fuel-air mixture exiting the canister is fed into the combustion engine. The current development with more fuel-efficient engine and hybrid driveline technologies forces more and more effective purge procedures of the canister to be able to comply with legal requirements for hydrocarbon emission.
Detailed description of thesis work:
* Simulation of heat transfer on adsorption and desorption of hydrocarbons in a non-adiabatic plug flow canister geometry with GT-Suite software. (The adsorption of hydrocarbons on activated carbon is an exothermic process).
* Thesis work includes experimental investigation on the effect of heat transfer on adsorption and desorption process.
* Sensitivity analysis of how heat transfer is conducted and evaluating results with experimental data.
* The goal of the master thesis is to develop a simulation method to be able to predict the effect of heat transfer on adsorption and desorption of hydrocarbons in a real geometry canister during a typical vehicle drive cycle.
Profile
* M.Sc. with knowledge in the area of Chemical Engineering, Physics or Mechanical Engineering. Experience in modeling plug flow reactors, heterogeneous reaction including adsorption and desorption of reactants and products, modelling of momentum, heat and mass transport in gaseous and porous media and general mathematical modeling in chemical engineering is highly valued.
* Previous experience with software GT-Suite or similar CFD-software is valued.
Duration
* Period: 1 semester, 30 ECTS points
* Starting date: January 2018
* Number of students: Suitable for 1-2 student.
Application
* Attach your resume and cover letter stating your interests within the given area and your thoughts and credentials.
* Please note that applications arriving later then the last application date will not be taken in consideration.
* Selection will be ongoing during the application period.
