Modelling the particle trajectory and melting behaviour of non-spherical ice crystal particles

Existing ice crystal icing codes commonly neglect non-spherical particle rotation behaviour. This leads to uncertainties in modelling as crystals are typically non-spherical. paper develops a two-dimensional framework model the trajectory and melting behaviour of rotating particles. Non-spherical translational rotational motions resolved using unit complex numbers. The effect on heat mass transfer is implemented sub-model dependent both Reynolds A test case flow through swan neck duct presented. validated comparison discrete phase ANSYS Fluent experimental water droplet impingement data. Comparison developed with other simplified tracking methods (without rotation) first conducted. These results show large differences trajectory, velocity melt ratio individual particles overall behaviours, especially for high aspect Particle can indirectly affect single particle’s its velocity.
