- Identifiers
- 3-D simulation; flow of incoming fresh air is called the gravity current; gravity current prior to backdraft in compartment with obstacles; experimental setus pf Gojkovic; experimental procedure of Gojkovic's experiments; gas composition inside and outside the compartment at the opening time; minimum size of obsticales that cause hydraulic jump; initial and boundary conditions; boundary condition for the container, obstacles, floor and the ambient; zig-zag case vs. free-obstacles case; ignition time, transit time and Froude number for both cases
