The use of the capacitive sensors for the study of condensation processes in the short heat pipes of low-temperature range. Calculation of the sensors
Annotation
The description of the automated capacitive meter of local thickness of working fluid condensatefilm in a short low-temperature range heat pipes are given. Thedesign, the calculation of the open compact capacitive sensors’capacitanceto carry out measurements of the working fluid film local thickness on the condensation surface within heat pipesare presented. Electrical field distribution above the end surfacesof the open capacitive sensor measuring electrodesin outer liquid dielectric is shown.The capacitance of compactsensor for four electrode diameters ismade. The results of sensor capacitance calculation for electrode dimeter of 100, 500, 1000 mcm fits the sensor capacitance data for electrode diameter of 250 mcm at all d/a parameters for all diameters of measuring electrode.
