Drag and lift calculation through a spatial impulsive surface interaction model in free molecule flow

Summary
A spatial impulsive interaction model is applied to the calculation of drag and lift coefficients for flat plate, sphere and circular cylinder with side-wind in “hyperthermal” free-molecule flow. Obtained results for flat plate are also compared with the corresponding coefficients calculated by Hurlbut and Sherman in1968 according to the Nocilla reemission model(1962).

Nel presente lavoro viene applicato un modello spaziale impulsivo di interazione superficiale[1] al calcolo dei coefficienti di resistenza e portanza per lamina piana, sfera e cilindro con deriva in regime di molecole libere con velocità ipertermiche. I risultati ottenuti per la lamina piana vengono confrontati con i corrispondenti coefficienti calcolati teoricamente da Hurlbut e Sherman nel1968 [3].
