Five Decades of Tackling Models for Stiff Fluid Dynamics Problems

Rationality - as opposed to ''ad-hoc'' - and asymptotics - to emphasize the fact that perturbative methods are at the core of the theory - are the two main concepts associated with the Rational Asymptotic Modeling (RAM) approach in fluid dynamics when the goal is to specifically provide useful models accessible to numerical simulation via high-speed computing.

This approach has contributed to a fr...
