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 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.
Excel spreadsheet available on most desktop or laptop computers can serve as an effective and inexpensive computational tool in a heat transfer course. This paper focuses on the application of “Solver” and “Goal Seek” functions of Excel in solving those heat transfer problems requiring iteration solution process.
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.

Example demonstrating how to model, and optimize the surface temperature of a heat conducting slab in Excel using ExceLab calculus functions.
27 Απρ 2023 · This article walks through the creation of a model for heat transfer in a jacketed tank, tracking performance over time, to construct cooling and heating curves. This is an example of a batch process where a fixed quantity of material is processed as a unit.
