Present work reports an experimental and a numerical investigation of an iso-octane spray impinging on a flat surface. The spray behavior of a single-hole axially-disposed injector was studied in a constant volume vessel by varying the injection pressure and the wall temperature ranged between 5.0-20.0 MPa and room to 573 K, respectively. The spray impingement captured by Mie-scattering and Schlieren technique and the measured data were used to assess existing droplet-wall interaction models. The effects of injection pressure and wall temperature on spatial and temporal evolution of the liquid and vapor phase were analyzed via numerical simulation.

Abstract
Present work reports an experimental and a numerical investigation of an iso-octane spray impinging on a flat surface. The spray behavior of a single-hole axially-disposed injector was studied in a constant volume vessel by varying the injection pressure and the wall temperature ranged between 5.0-20.0 MPa and room to 573 K, respectively. The spray impingement captured by Mie-scattering and Schlieren technique and the measured data were used to assess existing droplet-wall interaction models. The effects of injection pressure and wall temperature on spatial and temporal evolution of the liquid and vapor phase were analyzed via numerical simulation.| File | Dimensione | Formato | |
