Abstract EN
Natural flow rate and sweet peppers productivity in tropical greenhouse are improved by CFD simulation is the main objective of this research work.
Most of the greenhouse types today are in the arch shape.
To develop an improved greenhouse structure for the region, the arch type was built and used as the control model.
Mae Sar Mai agriculture research station under the royal project foundation was selected as the field test site.
Temperature sensors with data logger were installed to monitor variation of temperature inside the greenhouse.
The measured temperature data were used as the boundary conditions for the CFD analysis.
A new greenhouse model with two-step roof shape was designed and the air flow behavior was simulated by using CFD.
Regarding CFD results the air flow rate of the new model is about 39% higher than that of old model.
The maximum temperature of the new model is lower than that of the old one.
The sweet paper growths in both greenhouse models were measured and compared.
Results show that the new model obtains 4°C lower maximum temperature in day time, 97% in number and 90% in weight higher the first grade pepper productivity than the old one.
