🔀 Heat Exchanger Calculators 14 Calculators
Design and analyze heat exchangers using LMTD and ε-NTU methods. Parallel flow, counter flow, and multi-pass configurations.
LMTD Method
Parallel and counter flow heat exchanger analysis. Calculate required area, LMTD, effectiveness, and temperature profiles.
ε-NTU Method
Effectiveness-NTU analysis for all configurations: parallel, counter, cross flow, and shell-and-tube.
Double-Pipe Design
Complete double-pipe heat exchanger sizing with fouling factors and overall heat transfer coefficient.
Shell-and-Tube
Preliminary shell-and-tube design with correction factor F for multi-pass arrangements.
TEMA Shell-and-Tube
Full TEMA-level shell-and-tube sizing. Iterate required tube count, shell diameter, local heat transfer coefficients, and pressure drops.
HX Pressure Drop
Viscous friction and return head losses in shell and tube heat exchangers using TEMA standards.
Plate Heat Exchanger
Chevron Plate Heat Exchanger (PHE) rating and sizing. Model enlargement factor, convection coefficients, and port/channel drops.
Air Cooler / Finned Tube
Design and rate finned-tube air coolers. Model plate or spiral fins with Briggs & Young correlation and cross-flow effectiveness.
Pinch Analysis
Optimize process energy integration. Calculate hot/cold utility targets, recovery limits, and locate the pinch point using the Linnhoff-March method.
Air-Cooled Heat Exchanger
Rate and size air-cooled heat exchangers (fin-fan coolers) with API 661 guidelines and Briggs-Young correlations.
Compact Heat Exchanger
Colburn j and friction f factors for plain, louvered, offset strip, and wavy fins in compact heat exchangers.
Cooling Tower Design
Design and rate wet cooling towers using the Merkel integration method with Simpson's 5-point rule.
Multi-Effect Evaporator
Sizing of forward-feed multi-effect evaporators (1 to 6 effects) with boiling point elevation (BPE) correction.
Regenerative Heat Exchanger
Thermal analysis of rotary (Ljungstrom) and fixed-matrix regenerators with effectiveness-NTU and Cr* corrections.
