- Title
Validation of a Lattice Boltzmann Model for Transient Cryogenic Two-phase Flow.

- Abstract
A thermal lattice-Boltzmann model of a van der Waals gas was used to check its applicability to specific challenges in the numerical simulation of transient cryogenic two-phase flow in rocket engine feed systems. Three test cases were chosen to prove the model is capable of capturing the underlying physics. Overall correct representation of incompressible flow should be demonstrated by a lid-driven cavity. The capability of the model to handle shocks and supersonic flow is shown in a shock tube configuration. The last test case was chosen in order to show instantaneous evaporation by the formation of a single vapour bubble at a heated surface.
