Mathematical modelling of evaporation mechanisms and instabilities in cryogenic liquids
Mathematical modelling of evaporation mechanisms and instabilities in cryogenic liquids
In this thesis we propose a model for laminar natural
convection within a mixture of two cryogenic fluids with preferential
evaporation.
This full model was developed after a number of smaller
models of the behaviour of the surface of the fluid had been examined.
Throughout we make careful comparison between our analytical and computational
work and existing experimental and theoretical results.
The coupled differential equations for the main model were
solved using an explicit upwind scheme for the vorticity-transport, temperature
and concentration equations and the multigrid method for the Poisson equation.
From plots of the evolution of the system, it is found that convection becomes
stronger when preferential evaporation is included.
This new model demonstrates
how to include preferential evaporation, and can be applied to other fluid
systems.

Abstract
In this thesis we propose a model for laminar natural
convection within a mixture of two cryogenic fluids with preferential
evaporation.
This full model was developed after a number of smaller
models of the behaviour of the surface of the fluid had been examined.
Throughout we make careful comparison between our analytical and computational
work and existing experimental and theoretical results.
The coupled differential equations for the main model were
solved using an explicit upwind scheme for the vorticity-transport, temperature
and concentration equations and the multigrid method for the Poisson equation.
From plots of the evolution of the system, it is found that convection becomes
stronger when preferential evaporation is included.
This new model demonstrates
how to include preferential evaporation, and can be applied to other fluid
systems.
