NumericalExperiments to ObtainNusseltNumberforLaminar Fluid FlowPast an in-line tube bank

In this paper we want to get an equation forcomputing the mean Nusselt number in fluid flowpast an in-line tube bank with ellipse section.During this analysis we use numerical experimentsby using software and the flow is assumed to betow-dimensional. In order to discretizing therespective equations, finite volume method is usedand to improve the results we use the meshingboundary layer on the pipe surface. Clearly whenwe have the equations for Nusselt number, we cancompute the heat transfer without the numericalexperiments. For validation between solutionprocedure and software that is used, at first we tryto get the equation for fluid flow around the tubebank with circular section that has analytic solutionthen we compare them with the result of numericalexperiments. In order to compute the equation forevery Reynolds number, the mean Nusselt numbercalculated. We do this for several points. Then byusing the Hilpert experimental equation, alogarithmic equation is assumed and by drawingNusselt number and Reynolds number logarithmicdiagram, the equation will be obtained
