Use of inverse modelling techniques for the estimation of heat transfer coefficients to fluids in cylindrical conduits

摘要: Abstract We propose a method for the estimation of overall heat transfer coefficient to/from fluid in cylindrical pipe at high Peclet numbers from/to medium with unknown temperature profile axial direction. The uses an analytical solution equation coordinates subject to Robin boundary condition and parametrised, piecewise linear approximation external profile. velocity profiles both viscous turbulent flows are considered compact solutions evaluated cases as functions It is shown that these provide efficient from data based on separable least squares. procedure illustrated by numerical example using simulated data.
