1. 1. Conceptual design and development of thermal management system for hybrid electric aircraft engine. : A study to develop a physical model and investigate the use of Mobil Jet Oil II as coolant for aircraft electrical propulsion under different scenarios and time horizons.

   University essay from Mälardalens högskola/Framtidens energi

   Author : Yash Khanna; [2019]
   Keywords : Hybrid electric aircraft system; Thermal management system; micro channel; Dynamic modelling; Mobil Jet Oil II;

   Abstract : The ever-increasing levels of greenhouse gas emissions has led to the scientific community starting to explore the viability of electrical aircraft system, with the most prominent research and product development for hybrid electric system, which forms the transition phase from combustion to fully electric aircrafts. The primary objective of this thesis is to find solutions towards thermal management of the electrical components of a hybrid electric aircraft propulsion system, which generate a significant amount of heat while operating at heavy load conditions required to propel an aircraft.

3. 2. Evaluation of the wavefronts and spatial structures of ultrashort pulses passing through a micro-channel plate

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Simon Ek; [2019]
   Keywords : high-order harmonic generation; HHG; micro-channel plate; MCP; attophysics; Physics and Astronomy;

   Abstract : The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. READ MORE

4. 3. Experimental Investigation ofTwo-phase Flow in Microchannels“Co-current Absorption of Ammonia in Water to Design an Innovative Bubble Plate Absorber” : “Co-current Absorption of Ammonia in Water to Design an Innovative Bubble Plate Absorber”

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Ali Ammari; [2012]
   Keywords : Micro-channel; Ammonia-water; Two-phase; Absorption; Visual analysis;

   Abstract : For ammonia-water absorption refrigeration technology it is suggested to use bubble type absorbers because the higher contact surface area provides a higher mass transfer rate. Furthermore, dispersion of bubbles in the bulk of liquid phase also exhibits better heat transfer characteristics that facilitate the recovery of dissipated heat of the exothermic absorption.

5. 4. Investigations on Detector Non-Linear Response for the Optimization of Laser-Induced Phosphorescence Decay-Time Detection.

   University essay from Lunds universitet/Fysiska institutionen

   Author : Fahed Abou Nada; [2011]
   Keywords : avalanche photodiode; photodetector; non-linear detector response; phosphorescence; thermographic phosphor; photomultiplier tube; decay-time; time-gated detector; Physics and Astronomy;

   Abstract : This thesis investigates the nonlinear detector response to Laser Induced Phosphorescence signal originating from the CdWO4 phosphor. A matrix method is utilized to map the detectors linearity for decay-time determination as function of detector gain and number of photons reaching the detector. READ MORE
