1. 1. Developing a Mathematical Model of a Nuclear Thermal Rocket Engine

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Anton Blomqvist; [2023]
   Keywords : Nuclear Thermal Rocket; Nuclear Rocket; Rocket; Mathematical Model;

   Abstract : Renewed enthusiasm for space exploration brings more ambitious missions to light butthe constraints of chemical rockets put imposing limits on what is feasible. Nuclearthermal rockets provide an attractive and efficient alternative to shorten travel timesand increase payload. READ MORE

3. 2. Numerical approach of a hybrid rocket engine behaviour : Modelling the liquid oxidizer injection using a Lagrangian solver

   University essay from KTH/Mekanik

   Author : Gustave Sporschill; [2017]
   Keywords : Hybrid propulsion; combustion; numerical simulations; two-phase flow; La-grangian approach;

   Abstract : To access and operate in space, a wide range of propulsion systems has been developed, from high-thrust chemical propulsion to low-thrust electrical propulsion, and new kind of systems are considered, such as solar sails and nuclear propulsion. Recently, interest in hybrid rocket engines has been renewed due to their attractive features (safe, cheap, flexible) and they are now investigated and developed by research laboratories such as ONERA.

4. 3. Wall Condensation Modelling in Convective Flow

   University essay from KTH/Kraft- och värmeteknologi

   Author : Marcus Lejon; [2013]
   Keywords : condensation; modelling; CFD; fluid mechanics; thermodynamics; reactions;

   Abstract : Modelling condensation of water vapour is important in a number of engineering applications, such as nuclear reactor containment, rocket engine nozzles and heat exchangers. The current study investigates the possibilities of modelling condensation induced by a cold surface in a flow at high velocity and temperature. READ MORE
