“…There are several papers [26][27][28][29][30] that introduce analytical models which describe the flow distribution in manifolds. One that could be used to predict the velocity distribution, flow distribution, and pressure drop was shown in [26]:…”

Analysis of the state of-the-art in research of minichannel heat exchangers, especially on the topic of flow maldistribution in multiple channels, has been accomplished. Studies on minichannel plate heat exchanger with 51 parallel minichannels with four hydraulic diameters, i.e., 461 µm, 574 µm, 667 µm, and 750 µm have been presented. Flow at the instance of filling the microchannel with water at low flow rates has been visualized. The pressure drop characteristics for single minichannel plate have been presented along with the channels blockage, which occurred in several cases. The impact of the mass flow rate and channels' cross-section dimensions on the flow maldistribution were illustrated.

“…A great number of experimental, analytical, and numerical studies deal with flow in manifold. The flow in distribution manifold has been studied by several investigators [1][2][3][4][5][6][7][8][9]. In general, all previous studies for manifolds with different applications had shown that typical manifold design does not give a uniform flow distribution at outlets.…”

Abstract. This paper presents an analysis of fluid flow in a typical manifold. A commercially available Computational Fluid Dynamics (CFD) package has been used to analyze the flow pattern inside the manifold. Pressure drop in whole fluid domain and mass flow rate in all the outlets in the manifold have been computed. Based on the preliminary results, a modification to inside of the main pipe of the manifold has been incorporated. The performance of the modified design has been compared with the original design from the point of view of average temperature and mass flow rate at the outlets. A simple modification has been shown to improve the uniformity of temperature and mass flow at the outlets.
