Jafar, Farial A, Thorpe, Graham R and Turan, Ozden (2010) Falling film transition and heat transfer on horizontal circular cylinders. In: Proceedings of the 17th Australasian Fluid Mechanics Conference, 5-9th December 2010. Mallinson, G. D and Cater, J. E, eds. Auckland, N.Z., The University of Auckland.


In this paper, an investigati on of liquid film falling over three horizontal cylinders is presente d. A numerical investigation verified with experimental re sults is carried out using a computational fluid dynamics (C FD) code, FLUENT, for 2D and 3D configurations towards better design of beds of irrigated horticultural produce. The primary objective of the present study is to use numerical predictions to study the effect s of liquid flow rate, cylinder diameter and the heat flux towards reducing energy and water requirements in cooling horticultural produce. The present numerical results show good agreement with the experimental results. The use of a numerical tool has resulted in a detailed investigation of flow and heat transfer characteristics which have not been available in the literature previously.
