A two-pass internal cooling channel under the influence of rotation is experimentally and numerically investigated. Steady-state numerical simulations support the experimental method, which is based upon the temperature measurement with thermochromic

Volume 6B: Heat Transfer — General Interest/Additive Manufacturing Impacts on Heat Transfer; Internal Air Systems; Internal Cooling.
A test rig for the investigation of rotating turbine blade internal cooling channel configurations is presented. Local heat transfer distributions are evaluated using the transient thermochromic liquid crystal (TLC) technique. The rig can be operated

The existence of large-scale turbulent structures within a porous medium, generated through the interaction with a turbulent outer flow, is a highly debated topic, albeit most of the analysis is based on computational studies. This study contributes

An experimental approach to study unsteady local heat transfer characteristics due to airflow velocity and/or airflow temperature variations is presented. It uses controlled electrical heaters and rotating vanes to independently vary the flow and the

Thermocouples are often used for temperature measurements. Under transient conditions, measurement errors can occur due to capacitive inertia and heat conduction along the stem of the thermocouples. To correct such errors, a method is presented in Pa
