An Evaluation of Cooling Performance Analysis of Hyperbolic Cooling Towers with Computational Fluid Dynamics

Öz

In this paper, the flow analysis of a hyperbolic cooling tower with various inlet conditions is calculated using the computational fluid dynamics module. A cooling tower with a capacity of 50 tons/hour is taken as a reference. The system has two water inlets on the left and right sides and an air inlet at the bottom. As a result of the analysis, it is seen that the main factors affecting the performance of the cooling tower are fluid temperature and ambient humidity values. It is also calculated that the cooling performance increases if the tower height is designed at the optimum level. It is observed that the cooling capacity of the tower increases with the increase in air flow rate and flow rate. The k-Ɛ energy equation method was used in this analysis.

Bu makalede, çeşitli giriş koşullarına sahip hiperbolik bir soğutma kulesinin akış analizi, hesaplamalı akışkanlar dinamiği modülü kullanılarak hesaplanmıştır. Referans olarak 50 ton/saat kapasiteli bir soğutma kulesi alınmıştır. Sistemde sağ ve sol tarafta olmak üzere iki su girişi ve alttan hava girişi bulunmaktadır. Analiz sonucunda soğutma kulesinin performansını etkileyen ana faktörlerin akışkan sıcaklığı ve çevre nem değerleri olduğu görülmüştür. Ayrıca kule yüksekliğinin optimum seviyede tasarlanırsa soğutma performansının arttığı hesaplanmıştır. Hava debisinin ve akış hızının artması ile kulenin soğutma kapasitesinin arttığı gözlemlenmiştir. Bu analizde k-Ɛ enerji denklemi yöntemi kullanılmıştır.
