Effect of Various Coolant Mass Flow Rates on Sealing Effectiveness of Turbine Blade Rim Seal at First Stage Gas Turbine Experimental Facility

Energies, 2020
The appropriate coolant mass flow of turbine blade rim seal has become an important issue as turbine blades are exposed to increasingly higher thermal load owing to increased turbine inlet temperature.

Evaluating the Sealing Effectiveness of a Caprock-Fault System for CO2-EOR Storage: A Case Study of the Shengli Oilfield [PDF]

Geofluids, 2017
An effective sealing system is crucial for CO2-EOR storage, and these sealing systems are typically composed of the caprocks and faults that surround a reservoir. Therefore, the sealing effectiveness of a caprock-fault system must be evaluated at various

Sealing effectiveness of a novel NHS-POx based patch: experiments in a dynamic ex vivo porcine lung. [PDF]

J Thorac Dis, 2023
Background Sealants are used to prevent prolonged pulmonary air leakage (PAL) after lung resections (incidence 5.6–30%). However, clinical evidence to support sealant use is insufficient, with an unmet need for a more effective product.

Harmonisation of Coolant Flow Pattern with Wake of Stator Vane to Improve Sealing Effectiveness Using a Wave-Shaped Rim Seal

Energies, 2019
The rim seal of the gas turbine is intended to protect the material of the turbine disk from hot combustion gases. The study of the rim seal structure is important to minimise the coolant flow and maximise the sealing effect. In this paper, a wave-shaped
