Background
The overall objectives within Climate Comfort is to control indoor cabin environment based on law (and internal) requirements in order to ensure regulations for acceptable driving safety, visibility and human comfort are fulfilled. For this purpose CFD is an economical and powerful tool permitting a fast pace development and optimization of different systems, such as ducts and housings during a design process of the car while securing regulations.
Application areas for the above mentioned regulations typically concern pressure drop and mass flow distribution in ventilation system, human comfort analysis, side window demisting and windscreen defrosting analyses. Traditional approach for handling these type of problems has been to adopt solution techniques relying on simplicity and robustness without including additional disciplines for the problem in question.
Joint (rather than stand-alone) influence(s) of various flow types and disciplines adds additional dimension to the flow complexity and in turn might require unconventional solution procedures  otherwise typically not utilized in the industry. This opens up possibilities to shed light on the nature of the problem from another perspective and thereby tackle the analyses with greater level of understanding and accuracy which in essence becomes a core motivation for Climate Comfort to take a first step on this road together with curious and creative students.

Scope
The objectives of the thesis are:
•    Perform a thorough literature study with the purpose to map relevant physical flow phenomena occurring in a typical ventilation system analysis of car cabins.
•    Clearly understand and map limitations, potentials as well, with current CFD methodology.
•    Conduct a systematic investigation and critical assessments of suitable workflow procedures to resolve identified flow features in the virtual environment, and eventually implement necessary update to current 3D CFD method. Both preprocessing and postprocessing routines are expected to be considered at this stage. 
•    Prepare a process for validation of current and updated 3D CFD method. Link this work process to an evaluation of confidence and accuracy of the physical testing facility.
Critically asses the current measurement methodology, and if found required, propose alternative approaches and give motivation for final selection.
•    Conduct physical testing in the climatic chamber based on the taken approach from previous step and generate required road map for measurement of relevant fluid flow variables. 
•    Characterize any limitations with developed 3D CFD workflow and propose future method improvements.
