Heat exchanger design includes estimation of the heat transfer area needed for known or estimated heat transfer rate, overall heat transfer coefficient and log mean temperature difference. The tube or pipe diameters and length also need to be determined, as well as the pressure drop.
This paper focuses on the application of “Solver” and “Goal Seek” functions of Excel in solving those heat transfer problems requiring iteration solution process. It provides a collection of examples demonstrating the application of Excel in solving heat transfer problems.
This paper demonstrates how Excel can be used in solving heat exchanger problems. Formulas are provided for replacing charts in solving heat exchanger problems. Several examples are included to demonstrate the application of Excel in heat exchanger analysis and design.
A few examples include graphs for fin efficiencies, transient temperature distribution charts for heat transfer in slabs, cylinders, or spheres (Heisler Charts), heat exchanger correction factors, NTU-effectiveness charts, and radiation shape (view) factor charts.
10 Αυγ 2011 · The heat transfer rate, Q, can be calculated in a preliminary heat exchanger design spreadsheet if the flow rate, heat capacity and temperature change are known for either the hot fluid or the cold fluid. Then one unknown parameter can be calculated for the other fluid.
regulate efficient heat transfer from one fluid to another. There are two main types of heat exchangers. The first type of a heat exchanger is called the recuperative type , in which heat are exchanged
