Conclusions
As the result of investigation of the aerodynamics of the kiln cross section with charges of a tunnel circular kiln it was established that the uniformity in the velocity field across the width of the kiln cross section depends upon the composite influence of the charge parameters and the geometric and dynamic factors of the curvature.
The charge has a positive influence on the uniformity of the velocity field and the geometric and dynamic factors a negative one. The charge geometric parameters play the primary role in providing uniformity of the velocity field across the width of the kiln cross section. Providing uniformity in the velocity field across the width of the kiln channel cross section amounts to the creation of aerodynamically optimum charges.
From the results of the investigation it follows that calculation of the aerodynamics of tunnel circular kilns may be done using the equations of tunnel kilns.
