| Abstract: | According to the rule of restricted attachment jet in blind drift and the calculation of its characteristic parameters,the relationship between the outlet diameter of the windsocks and the flow field,and the one between the outlet velocity of windsocks and the change of jet axial velocity are analyzed.It is concluded that the characteristic parameters of the restricted attachment jet have a great influence on the flow field.The study on the relationship between the characteristic parameters and flow field will be more helpful to the monitoring of air environment in blind drift.,and thereby to the improvement of the work environment and safety coefficient. |
