1. Turbo For Fuel Cell Electric Vehicle
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. LÄS MER
2. Towards Automatic and Systematic Compressor Model Selection Based on Measurement Data
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : Centrifugal compressors are mechanical devices that move and compress gas and are used in a wide range of applications. To get as much efficiency out of the compressors as possible, high demandsare put on having good compressor models. LÄS MER
3. Modelling and Simulation of Fan Performance using CFD Group
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Performance of vacuum cleaners are affected by factors such static pressure, airflow rate and efficiency. In this thesis work, attempt has been made to design a fan to meet the requirements of suction static pressure and air flow rate and in the process understand the fan design parameters that affect these performance parameters.

4. Assessment of a One Dimensional Loss Model For The Compressor of a Turbocharger
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : This report sets out to implement and asses a one-dimensional loss model for centrifugal compressors. The loss model which has been evaluated is the model by Oh et al. (1997) [1]. The implementation was completed using iterative methods implemented in Matlab. LÄS MER
5. Performance and model calibration ofhigh-pressure compressors
Master-uppsats, KTH/EnergiteknikSammanfattning : To fully determine the performances of high-pressure compressors (HPC), modeling and partial tests can beperformed to characterize its different operating conditions. Nevertheless, there are still noticeable errorsbetween the results of these models and the tests: deformations and differences can appear, and notably becauseof a modeling defect or the assumptions made during the analysis (measurement corrections for example).
