Areas of air inlet and outlet openings, orientation of
openings, height difference between air inlet and outlet openings, wind
direction, greenhouse geometry, and type of plant grown are among the many
factors that should be taken into consideration in designing an effective
ventilation system for greenhouses. In this study, five different model plastic
greenhouses with different sidewall heights, air inlet and outlet opening areas
and roof shapes were used to evaluate the ventilation efficiencies and they
were compared with a conventional type of the region. A computational fluid
dynamics (CFD) program was used to evaluate the behavior of the internal
environment (internal flow rate and temperature distributions) and natural
ventilation rates for all model greenhouses and a conventional greenhouse
involved in the study. External wind speeds of 0.5, 1, and 2 ms-1

were used in the simulations for all conditions. The results of simulations and
experimental studies were evaluated and used for recommendation of a better
greenhouse model for this region. CFD software “FLUENT” was used to determine
the effectiveness of greenhouse ventilation system and k-ɛ Renormalization
Group (RNG) turbulence model was used in solutions.

Hava giriş ve çıkış
açıklıklarının alanları, konumları, giriş ve çıkış açıklıkları arası yükseklik
farkı, rüzgar yönü, sera geometrisi ve serada yetiştirilen bitki çeşidi gibi
birçok faktör havalandırma sisteminin planlanmasında etkili olmaktadır. Bu
çalışmada havalandırma sistemlerinin etkisini değerlendirebilmek amacıyla
farklı yan duvar yüksekliğine, havalandırma giriş çıkış açıklıklarına ve sera
çatı şekillerine sahip beş farklı özellikte plastik sera kullanılmış ve bu sera
modelleri ile bölgede kullanılan tipik sera modeli karşılaştırılmıştır.
Çalışmada kullanılan tüm sera modellerinin iç çevre koşulları (hava akış hızı
ve sıcaklık dağılımları) ve hava değişim oranları Hesaplamalı Akışkanlar
Dinamiği (HAD) ile değerlendirilmiştir. Simülasyonlardaki tüm koşullar için dış
hava hızı 0.5, 1 ve 2 ms-1 olarak belirlenmiştir. Sera içi etkili
havalandırma sisteminin çözümünde HAD’nin
“FLUENT” yazılım
programından yararlanılmıştır. Çözümde ise türbülans modeli olarak
k-ɛ Renormalization Group
(RNG) türbülans modeli kullanılmıştır
