Simulations of hypersonic, high-enthalpy separated flow over a 'tick' configuration

Correlation for Length of Impinging Shock-Induced Large Separation Bubble at Hypersonic Speed

“…Often, the separation occurs very close to the leading edge, where the boundary layer is insignificantly thin. Studies on leading edge separation at hypersonic high enthalpy conditions have only been initiated in recent years [6].…”

Hypersonic High-Enthalpy Flow in a Leading-Edge Separation

“…The paper also highlights the differences between the high and low enthalpy (low and high density) flow results, which was not considered in Moss et al [5]. Figure 3a shows the comparison of normalised pressures between perfect-gas Navier-Stokes (N-S) and non-reacting gas DSMC simulations.…”

“…The DSMC calculations were carried out using DS2V [1]. The full details of the DSMC simulations carried out for the present configuration are given in Moss et al [5].…”

Factors influencing flow steadiness in laminar boundary layer shock interactions

“…Moss and Bird [8] compared DSMC simulations for flow over a double cone configuration and obtained excellent agreement with heat flux measurements for a Knudsen number case about a factor of three larger than what will be presented in this work. Finally, more recent modeling and experiments [9] show that the impact of the slip velocity has a significant impact on the size of the separation region by comparing Navier-Stokes (NS) and DSMC solutions for a "tick" configuration in the near-continuum regime. The separation size predicted by NS is larger than DSMC due to the zero slip assumption which is an obvious shortcoming of the solution.…”
