Relationships between local topology of vortical flow and pressure minimum feature derived from flow kinematics in isotropic homogeneous turbulence

Journal of Fluid Science and Technology, 2016
Relationships between local flow topology (geometry) of vortical flow and pressure minimum feature derived from its flow kinematics are investigated in isotropic homogeneous turbulence, in a new topological point of view with respect to vortical flow ...

Quantifying Swirl Number Effects on Recirculation Zones and Vortex Dynamics in a Dual-Swirl Combustor

Energies
Swirl-stabilized combustors are central to gas turbine technology, where the swirl number critically determines flow structure and combustion stability. This work systematically investigates the isothermal flow in a dual-swirl combustor, focusing on two ...

Swirling flow generators and swirling flow seperators

, 2020
Bu tezde sunulan çalışmada, dönü üreteçleri ve parçacık ayırıcıları üzerine bir literatür araştırması yapıldı. Teğetsel giriş yüksekliği ve genişliği, akışkan çıkış borusu çapı ve derinliği, artık parçacık çıkış çapı, ve koni yüksekliği biri birinden bağımsızca değiştirilebilen bir siklon parçacık ayırıcısı tasarlanıp imal edilmiştir.
