Heat Transfer Calculations during Flow in Mini-Channels with Estimation of Temperature Uncertainty Measurements

The main aim of this work was to provide heat transfer calculations flow boiling in mini-channels with an application for the Trefftz functions. test section comprised five parallel a depth 1 mm, common heated wall. For estimation temperature uncertainty, during experiment measurement performed use K-type thermoelements and infrared camera two simultaneously. According Guide Expression Uncertainty Measurement, Monte Carlo method is practical alternative GUM uncertainty framework. Since components are not approximately same magnitude, indicated estimate surface measurement. results obtained from simulation were compared computation related propagation method. both methods found be consistent. statistical analysis used describe calculations. investigations concerning subcooled region other experiment. local coefficients on contact between working fluid wall calculated Robin boundary condition. mathematical model described by equation mini-channel Fourier-Kirchhoff flowing leads inverse problem. This problem solved using FEM Trefftz-type basis measurements due included final coefficient.
