A turbine blade for a turbine engine having a cooling system in the turbine blade formed from at least one cooling channel. The cooling channel may be a serpentine cooling channel with a flow guide extending from a first turn to a second turn of the cooling channel and formed from a first turn section, a second turn section, and a body coupling the first and second turn sections together. The flow guide substantially eliminates separation of cooling fluid flow in the tip region of the cooling channel, thereby increasing heat transfer. In at least one embodiment, the flow guide extends from a first turn in the cooling channel proximate to the blade tip to a second turn proximate to a root of the blade.
