ABSTRACT:
A turbine blade for a turbine engine having a cooling system in the turbine blade formed from at least one cooling channel. The cooling system may include one or more protrusions positioned in the cooling channel and including one or more vortex breakers along the length of the protrusion. The vortex breakers disrupt vortices formed downstream of the protrusions to increase heat transfer enhancement effect of the protrusions. The cooling channels of the cooling system may include a plurality of protrusions whose configuration is based upon the cooling requirements of the blade in which the cooling system is installed.
