Numerical study and experimental validation of a Roots blower with backflow design

Engineering Applications of Computational Fluid Mechanics, 2018
A three-dimensional computational fluid dynamics (CFD) model of a Roots blower with a backflow design was established to analyse the effects of the backflow on the Roots blower's performance.

Development of an Air Duct Damper to Prevent Backflow Odor from the Ventilation Shaft in Buildings

Journal of Asian Architecture and Building Engineering, 2017
Nowadays, backflow odor, along with floor noise, has been recognized as an environmental right dispute element between the units within a multi-unit dwelling in Korea because it causes not only foul odors flowing back into the unit vent pipe to flow ...

Quantum backflow for two identical particles [PDF]

New Journal of Physics
Quantum mechanics introduces the possibility for particles to move in a direction opposite to their momentum—a counter-intuitive and classically impossible phenomenon known as quantum backflow. The magnitude of this effect is relatively small, making its

Observation of Backflow during the Anihilation of Topologocal Defects in Freely Suspended Smectic Films

Crystals, 2021
Freely suspended films in the smectic C phase are excellent templates for the study of topological defect dynamics. It is well known that, during the annihilation of a pair of disclinations with strengths +/−1, the +1 defect moves faster because it is ...

Study on back-pressure propagation and suppression of single pulse detonation

Xibei Gongye Daxue Xuebao, 2023
The backflow and back-pressure propagation induced in a pulse detonation combustor (PDC) are the main factor in causing the thrust losses of a pulse detonation engine.

Research on Energy Saving of PHEV Air Conditioning System Based on Reducing Air Backflow in Underhood

Energies, 2022
A novel method characterizing the air backflow of the underhood in order to improve the thermal efficiency of the air conditioning system (ACS) and reduce the energy consumption of PHEV is proposed in this paper. In addition, a 1D model for analyzing air

Effects of stable clearances on backflow in the variable-pitch screw vacuum pump

Mechanics & Industry, 2021
Effects of various clearances of variable-pitch screw vacuum pump on gas backflow of internal flow field of the pump cavity is studied. The theoretical tooth surfaces of screw rotor are optimized by radial, normal equidistance modifications, and four ...
