Ventilation Grille Model IB-RCorrection factor (for scattered air jet) Blade position opposite to one another (-LGEG) Blade position straight diverging Blade position The angle of propagation of the air jet and thus the length of throw can be affected by adjusting the vertical air deflection blades. Layout example Assume: Ventilation grille IB-R-08-... H = 115 mm L =615 m (with coanda effect) x =6.0 m Find: Pressure loss, sound level, end velocity of jet, critical throw, induction and temperature ratios.
