Bu çalışmada, merkezi havalandırma sistemi davlumbaz tasarımının yakalama performansı üzerindeki etkilerinin araştırılması amaçlanmıştır. Davlumbaz tasarımını optimize etmek ve yakalama performansını tahmin etmek için ticari hesaplamalı akışkanlar dinamiği (HAD) yazılımı kullanılmıştır. HAD yazılımı sayesinde gerçek ölçülere sahip davlumbaz modellenmiş ve sayısal analizler gerçekleştirilmiştir. Sayısal analizlerde, davlumbaza eklenen hava yönlendirici kılavuz sayesinde davlumbaz kaputunda oluşan türbülanslı akış engellenmiştir. Bu sayede, davlumbaz yakalama hızında ve hava debisinde artış sağlanmıştır. Yapılan HAD analizleri sonucu elde edilen bilgiler ile davlumbaz prototipleri oluşturulmuş ve gerçek ortam deneyleri yapılmıştır. Farklı debi değerlerinde gerçekleştirilen sayısal analizler, deneysel analizler ile doğrulanmıştır. Sonuç olarak HAD analizleri, davlumbaza eklenen hava yönlendirici kılavuzun, hava akışında oluşan türbülansı engellediğini ve davlumbaz performansını artırdığını göstermiştir.

A Study on Increasing the Efficiency of Central Ventilation System Kitchen Hoods

Öz

In this study, it is aimed to investigate the effects of central ventilation system hood design on capture performance. Commercial computational fluid dynamic (CFD) software was used to optimize the hood design and predict capture performance. Thanks to the CFD software, the hood with real dimensions was modeled and numerical analyzes were carried out. In numerical analysis, the turbulent flow in the hood was prevented by the air guide attached to the hood. In this way, an increase was achieved in the hood capture velocity and airflow rate. With the information obtained as a result of CFD analysis, hood prototypes were created and real environment experiments were carried out. Numerical analysis performed at different flow rates were confirmed by experimental analyzes. As a result, CFD analysis showed that the air guide added to the hood prevents turbulence in the air flow and increases the hood performance.
