Segmental pin and endwall heat transfer for a staggered pin fin array in a stationary and rotating channel

An experimental study is conducted to separate the heat transfer contributions of the pin surfaces and endwalls in a staggered circular pin fin array subjected to straight flow ejection in a low aspect ratio rectangular channel, representative of gas turbine trailing edge cooling...

Ventilation and heat exchange characteristics in aircraft cabin considering buoyancy-driven flow and pressure-induced variations

During flight, aerodynamic heating and multiple internal heat loads create a high-temperature low-pressure extreme environment. The flow and heat transfer mechanisms there differ from those in atmospheric sealed chambers, posing substantial challenges to thermal control design. M...

Study on Contact Characteristics of Aeronautical Floating Splines Considering Maneuvering Deformation

Floating involute splines are widely used in aviation power transmission systems for torque transmission. In this study, a finite element model considering the dynamic deformation of a floating involute spline shaft was established to analyze the influence of shaft deformation on...
