Prediction of distance to maximum intensity of turbulence generated by grid plate obstacles in explosion-induced flows

The interaction of unburnt gas flow induced in an explosion with obstacle results the production turbulence downstream and acceleration flame when it reaches this turbulence. Currently, there are inadequate experimental measurements these turbulent flows explosions due to transient nature connected harsh conditions. Hence, majority properties obstacles done using steady-state rather than flows. Consequently, empirical based correlation predict distance maximum intensity explosion-induced available steady state experiments was developed study. would serve as a prerequisite for determining optimum spacing between thereby worst case overpressure speeds. Using limited work on systematic study spacing, validated against 13 different test A ratio from experiment, xexp predicted xpred all tests 2-4. This shows that factor three higher be required produce will lead severity. In planning layout new installations, is appropriate identify relevant separation order avoid it. assessing risk existing installations taking mitigation measures important evaluate such basis clear understanding effects congestion. It therefore suggested various correlations obtained subjected further rigorous validation data prior been applied design tools.
