Heat Transfer: Top 5 Apps for Thermal Design

Apps for many common sales and engineering tasks encountered on a daily basis in heat exchanger industry have been developped in recent years.

Here below the Top 5 for Heat Transfer Thermal Design

Current version of Heat Exchanger Toolbox includes the following Apps:

UnitEng: Unit converter specifically customized for process engineers

LMTD: Quick LMTD calculator for co-current and counter current flows

Heat Balance: Determine a consistent set of temperature, flow rate and thermal duty based on thermal balance

Shear Stress: Estimate surface shear stress based on overall pressure drop

 

Flow V: Calculate average fluid velocity through pipes or heat exchanger nozzles

Pipe DP: Calculate pressure drop through pipes for fully developed flow with a convenient lookup feature for standard pipes and specified surface roughness 

                                                                            


     

Pumping Power: Calculate pumping power and motor power based on static and dynamic pressure drop

Thermal Expansion: Estimate linear or volumetric thermal expansion with a convenient lookup feature for commonly used materials

Pipe Dim: Pipe dimension lookup for OD, ID, Internal volume from a list of NPS pipe sizes and schedules

Fouling on the heat transfer surface during operation of a heat exchanger reduces the overall heat transfer coefficient (U value), and therefore, the thermal performance.

This App allows user to quickly calculate the actual overall heat transfer coefficient (dirty U value) based on clean U Value and the fouling factor.

User can conveniently choose preferred input and output units directly besides each input box and on the result panel.
