Understanding our future through Open Access research about our past...

Strathprints makes available scholarly Open Access content by researchers in the Centre for the Social History of Health & Healthcare (CSHHH), based within the School of Humanities, and considered Scotland's leading centre for the history of health and medicine.

Research at CSHHH explores the modern world since 1800 in locations as diverse as the UK, Asia, Africa, North America, and Europe. Areas of specialism include contraception and sexuality; family health and medical services; occupational health and medicine; disability; the history of psychiatry; conflict and warfare; and, drugs, pharmaceuticals and intoxicants.

Abstract

Numerical simulations of high-speed, high-altitude flow over re-entry objects have been carried out for a variety of flow conditions corresponding to test cases proposed for the 1st Spacecraft Demise Workshop. In the continuum regime, conventional computational fluid dynamics (CFD) has been employed to characterise the aerothermodynamic loads acting on the bodies and to predict the shock structures in the surrounding flow fields. In the upper atmosphere, transition-continuum regime the direct simulation Monte Carlo (DSMC) approach has been applied using the quantum-kinetic (Q-K) chemistry model to account for the dissociation of nitrogen. Both CFD and DSMC approaches have been applied within the framework of the open-source CFD toolbox OpenFOAM.
