Numerical analysis of microchannel flow in vaporizing resistojet thrusters

In this report a master thesis work in support to the development of a water-based Vaporizing Liquid Microthruster (VLM) is presented. This device, which makes use of MEMS technology to offer a very high degree of miniaturization, is an extremely compact thruster which achieves an important performance (Isp > 100 s [64]) while utilizing water...

Hydraulic modelling of liquid-solid fluidisation in drinking water treatment processes

In drinking water treatment plants, multiphase flows are a frequent phenomenon. Examples of such flows are pellet-softening and filter backwashing where liquid-solid fluidisation is applied. A better grasp of these fluidisation processes is needed to be able to determine optimal hydraulic states. In this research, models were developed, and...

The effect of sloshing in partially filled spherical LNG tanks on ship motions

This report describes two methods to analyse the effect of sloshing on ship motions. The first method applies linear potential theory on both the barge and the internal tanks. For the barge the radiation, diffraction and incoming wave potentials are solved. For the internal tanks only the radiation potential is calculated, as there are obviously...
