Description

Heisler Calculator is a professional quality evaluation tool that quickly calculates internal temperatures for transient heat conduction through a 1-D plane wall of thickness 2*L. No more Heisler Charts! Heisler Calculator provides an accurate numerical solution, eliminating the need for tedious graphical results from Heisler charts. Heisler Calculator allows inputs in either SI (metric) units I-P (English) units, and converts from one to the other. The User Inputs: • x (the spatial location in the plane wall, measured from the centerline) • L (2L is the wall thickness) • t (the elapsed time since the step change in surroundings temperature) • h (the convective heat transfer coefficient) • k (the thermal conductivity  of the wall material) • α (the thermal diffusivity of the wall material) • Ti (the initial uniform temperature of the wall) • T∞ (the constant surroundings temperature far from the wall) Heisler Calculator Outputs: • x* (dimensionless distance from the center) • Fo (the Fourier Number, dimensionless time) • Bi (the Biot Number, dimensionless convective heat transfer coefficient) • θ* (dimensionless Temperature, =(T-T∞)/(Ti-T∞)) • T (temperature at x at time t) Limitations: • the wall is initially at uniform temperature • the temperature of the surroundings and the convective heat transfer coefficient are constant and uniform • no heat generation inside the wall • the Fourier number (αt/(L^2)) must be > 0.0001 • the wall and surroundings are symmetric around the wall centerline If you have a question or suggestion, please email heislercalc@blumtnwerx.com
