摘要：

In the study, experimental and numerical study have been conducted with microtubes having diameters range between 50 and 150 mu m to investigate viscous heating effects on the single-phase water flow. In the experiments temperature rises due to viscous heating have been measured under adiabatic conditions. Numeric analysis of flow through the adiabatic microtubes was performed by taking into account viscous heating effects using by computational fluid dynamic (CFD) code ANSYS CFX 12.0. CFD results were compared both experimental and analytical model results.
