Closed-loop bulk air conditioning: A renewable energy-based system for deep mines in arctic regions
International Journal of Mining Science and Technology, 2020 With depletion of shallow deposits, the number of underground mines expected to reach more than 3 km depth during their lifetime is growing. Although surface cooling plants are mostly effective in mine air-conditioning, usually secondary cooling units ...

A Multifidelity Aero-Thermal Design Approach for Secondary Air Systems
Journal of Engineering for Gas Turbines and Power, 2021 Abstract The paper presents a multidisciplinary approach for aero-thermal and heat transfer analysis for internal flows. The versatility and potential benefit offered by the approach are described through the application to a realistic low pressure turbine assembly.

Transient modelling and simulation of gas turbine secondary air system [PDF]
Applied Thermal Engineering, 2020 Abstract The behaviour of the jet engine during transient operation and specifically its secondary air system (SAS) is the point of this work. This paper presents a methodological approach to develop a fast, one-dimensional transient platform for preliminary analysis of the flow behaviour in gas turbine engines secondary air system. For this purpose,

The Effect of the Purge–Mainstream Density Ratio on Rim Seal Fluid Mechanics
International Journal of Turbomachinery, Propulsion and PowerSignificant density ratios arise in a gas turbine due to severe temperature gradients between the hot mainstream gases leaving the combustor and the superposed purge flow injected from the secondary air system. Engineers seek to minimise the ingestion of
