Optimization of radial airflow path of water vapor inside a scraped film evaporator

Physics of Fluids, Год журнала: 2025, Номер 37(3)

Опубликована: Март 1, 2025

Optimizing the radial airflow path of water vapor helps to improve evaporation efficiency scraped-film evaporator, thus contributing overall yield. Establishing a three-dimensional steady-state numerical simulation model gas phase in evaporator investigates flow characteristics vapor. And deflector was introduced optimize path, and deflecting effect comprehensively evaluated based on three indexes: vortex intensity, flux ratio, axial flux. Studies have shown that there is phenomenon during vapor, causes collect surface, inhibiting efficiency. The introduction can effectively weaken strength, distribution, guide area, increasing discharge velocity. By comparing analyzing structure different deflectors considering flux, optimal scheme finally determined. significantly reduced area by 60.57% increased region 15.6%. This study not only important optimizing performance scraped film but also achieves accelerating pumping power above, achieving energy saving emission reduction.

Analysis of Resistance Characteristics and Research into Resistance Reduction of a Tee Based on Field Synergy

Buildings, Год журнала: 2024, Номер 14(5), С. 1271 - 1271

Опубликована: Май 1, 2024

The resistance loss and energy consumption when fluid flows through a tee in an HVAC system are severe. To improve efficiency reduce carbon emissions, novel with U-shaped deflector is proposed, supported by experiments numerical simulations. reduction mechanism of the was analyzed according to viscous dissipation principle field synergy principle. different angles traditional were compared. results show that mainly due flow separation deformation main branch. relationship between local coefficient diameter ratio main-branch pipe exponential, straight linear. total rate addition 26° highest, reaching 72.4%, volume-weighted average angle increased 1°, decreased 21.7%. This study provides reference for design complex components such as tees systems.
