These ice particles undergo complex motions under the high-speed air flow near the surface (possibly including a boundary layer). Mathematical models could provide accurate predictions and insights to aid the design of new icing protection systems and safety tests. In this thesis, I have therefore developed mathematical models for particles moving in high-Reynolds number flow near a surface. Various scenarios are considered, including a particle moving within an air boundary layer, firstly in the middle boundary layer such that the flow is inviscid, and then later in the lower boundary layer with viscous-inviscid interaction. Aircraft may also become coated in a layer of water due to impact from droplets in the atmosphere, and so I develop models for particles interacting with water on the surface, including sinking and skimming on a water layer and a particle submerged in water. Mathematical analyses and computation are used in tandem here. date: 2024-04-28 date_type: published full_text_type: other thesis_class: doctoral_embargoed thesis_award: Ph.D language: eng verified: verified_manual elements_id: 2270306 lyricists_name: Jolley, Ellen lyricists_id: EMJOL34 actors_name: Jolley, Ellen actors_id: EMJOL34 actors_role: owner full_text_status: restricted pages: 138 institution: UCL (University College London) department: Mathematics thesis_type: Doctoral citation: Jolley, Ellen Mary; (2024) Fluid-body interactions near a solid surface.
