HTRI R-trend^®

HTRI R-trend calculates and trends the fouling resistance for shell-and-tube heat exchangers in single-phase service. This Microsoft^® Excel^® spreadsheet contains an interface to Xist^®.

Graphing options versus time are available for any two input and/or output parameters.

Required Inputs	Process Data	5 of the following 6 parameters: Cold fluid inlet temperature Cold fluid outlet temperature Hot fluid inlet temperature Hot fluid outlet temperature Cold fluid flow rate Hot fluid flow rate
	Heat Exchanger Geometry	With Xist	*.htri file with geometry specified
		Without Xist	Heat transfer area Number of tubepasses
	Fluid Properties	With Xist	*.htri file with hot and cold fluid properties specified
		Without Xist	Specific heat of hot and cold fluids Clean U
Calculated Outputs	Duty Heat balance Effective mean temperature difference Service U and clean U Fouling resistance and fouling Biot number (non-dimensional fouling number) Wall temperature (optional) Shear stress (optional)
