1. Empirical Verification of an Acoustic Estimation of a Rocket Engine : A Comparison Between Estimated and Measured Noise of a Rocket Engine
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The noise of a rocket engine is a complex and complicated phenomenon which has been studied for more than half a century [1]. There are many sources to this noise, but due to its great potential impact to the surrounding structures, including the vehicle itself, it is important to have a model to estimate the acoustic environment the engine produces.

2. A parametric study of oil-jet lubrication in gear wheels
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : A parametric study of oil-jet lubrication in gear wheels is conducted using Computational Fluid Dynamics (CFD) to study the effect of the different design parameters on the cooling performance in a gearbox. Flow in oil jet lubrication is found to be complex with the formation of oil ligaments and droplets. Various hole radii of 1.5, 2 and 2. LÄS MER
3. Numerical study of surface heat transfer enhancement in an impinging solar receiver
Master-uppsats, Uppsala universitet/Fasta tillståndets fysikSammanfattning : During the impinging heat transfer, a jet of working fluid, either gas or liquid, will besprayed onto the heat transfer surface. Due to the high turbulence of the fluid, the heat transfer coefficient between the wall and the fluid will be largely enhanced. LÄS MER
4. Computational study of multiple impinging jets on heat transfer
Master-uppsats, Avdelningen för bygg- energi- och miljöteknikSammanfattning : This numerical study presents investigation of impinging jets cooling effect on a hot flat plate. Different configuration of single jet, 5-cross and 9-square setups have been studied computationally in order to understand about their behaviour and differences behind their physics. LÄS MER
5. Numerical Study on the Thermal Performance of a Novel Impinging Type Solar Receiver for Solar Dish-Brayton System
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : An impinging type solar receiver has been designed for potential applications in a future Brayton Solar Dish System. The EuroDish system is employed as the collector, and an externally fired micro gas turbine (EFMGT) has been chosen as the power conversion unit. LÄS MER
