内容記述
A purpose of this paper is measurement of the heat flux at the collecting part of beam-down solar concentrator. The thin film type heat flux sensor that we made is used to measure a heat flux. The sensor can measure a heat flux at unsteady state. Therefore the sensor can measure a heat flux in a s hort t ime. T hat is a m erit o f t his m easurement system. The measurement in a short time enables a measurement at the operation time of the receiver. Seven heat flux sensors are used to obtain the distribution of heat flux at the collecting part of beam-down solar concentrator. The traverse device is used to move the sensors passing through the collecting part. The amplification circuits are used to amplify the output from the sensors 10,000 times individually. As results of measurements the two-dimensional distributions of heat flux were obtained using the measurement system in a short time. However the absorption factor of the heat flux sensors are used the value obtained in past study. So the absolute value of the output data is not correct. It is necessary to demand the absorption factor of heat flux sensor to know the accurate value.
