Meaning Behind Secondary Loss. Secondary losses are the other losses that come with losing a loved one. This could be a physical object, a tradition that involved the deceased, or something else. Often, these secondary losses appear over time rather than all at once.
Airfoil embodying mixed loading conventions
A high-lift airfoil embodying a combination of loading conventions in a single design specifically to reduce and control total pressure losses that occur in the flow channels between airfoils employed in turbomachinery applications is disclosed herein. The mixed-loading high-lift airfoil designs embody and exhibit the best total profile and secondary loss characteristics possessed by both aft-loaded airfoil and front-loaded airfoil conventions through controlling the development and interaction of boundary layers forming along the surfaces of the airfoils and the endwalls in such applications. The mixed-loading high-lift airfoil may be utilized in both rotating and non-rotating turbomachinery applications.
