Based on the change of the cross section in blade internal cooling channel rib caused by the
service wear, starting from the widely used rectangular cross section, the most likely …

A wavy rib is presented and its influences on the performance of a non-rotating straight
channel are studied numerically. For each geometric parameter of wavy rib, the target …

Wavy rib is a kind of novel turbulator that can effectively improve the ribbed wall heat transfer
of cooling channel and produce acceptable friction loss. Meanwhile, it has the advantage of …

Ribbing the internal passages of turbine blades with 45 deg inclined ribs is a common
practice to achieve a good compromise between high heat transfer coefficients and not too …

The increase of inlet gas temperature will lead to security problem of turbine blades. Internal
cooling channels are usually used to ensure the safe operation temperature of the turbine …

Rib turbulators are widely applied in internal cooling channels of gas turbine blades to
