Abstract
In this essay, to satisfy the need for highest rate of heat release, the triplex pipe was equipped with fins on both pipes. Nanomaterial has been utilized to expedite the process involving single phase approximation for modeling purpose. The equations have been simplified with involving the approximation of no sensible impact of convection and solutions have been obtained via Galerkin method. Good accommodation for this method was reported with incorporation of implicit technique for transient terms. Adaptive patterns of grid have been used to reach more accurate solution. With rise time, SF augments and magnitude of heat release decreases. With change of shape from cylinder to blade one, the completion time reduces around 5.6 %. Dispersing nanomaterial causes reduction of period of freezing about 22.97 %. Quickest process needs 791.3 s to complete the solidification which is happened when phi = 0.04 and m = 8.6.
