On the conjugate heat transfer method: Numerical study and an application case of optimization for a gas turbine transition piece cooling

Gas turbines (GT) play a crucial role in the transition to fully sustainable energy. Conversely, the expected growth of the GT market is met with more stringent regulatory requirements. Clearly, an increasing turbine inlet temperature (TIT) is beneficial for the efficiency of GT cycles. With increasing TIT, however, the magnitude of the thermal...

Convection in porous media: A numerical study of a side heated cavity with spatially varying conductivities using the conjugate heat transfer model.

Porous media are used for a wide variation of applications in energy production and storage. One of those applications is the storage of heat which are of great importance in the renewable energy transition. Most literature reported limit itself only to one single thermal conductivity for the porous media. In reality however, the porous media...

On the turbulence modeling and conjugate heat transfer study of the cooling system of the Beam Dump Facility target at CERN: Steady and Transient analysis

The Beam Dump Facility (BDF) is a new fixed target facility proposed to be installed in the North Area of CERN. Currently in its design phase, the BDF is aimed at the Search for Hidden Particles (SHiP) experiment, which purpose is to investigate the origin of dark matter and other lightly interacting particles. The BDF target/dump sits at the...

A Conjugate Heat Transfer Method Applied to Turbomachinery

A Conjugate Heat Transfer (CHT) analysis allows the calculation of the heat transfer and temperature of a body placed in a fluid. The CHT analysis takes into account both the conduction in the solid and the convection in the fluid. Present paper describes a CHT method that uses two separate solvers: one CFD solver dedicated to the flow...
