Modeling the process of high thermal radiation on the basis of irradiance

Abstract

Purpose. Study of the conditions in the workplace with an excessive thermal radiation currently has a number of difficulties: overheating devices and as a consequence, reduction of measurement accuracy, thermal overload by the researcher. Evaluation of sanitary and hygienic working conditions with thermal over voltage calculation methods is also accompanied by errors of averages and generalizations. This reduces the reliability of the defined parameters. There is a need to search for new and better methods for studying the climate heating, based on the calculated and experimental approaches. Methodology. The proposed method is based on physical modeling study of thermal energy irradiance workspace. To obtain reliable results, the following criterion has been formulated: device must set the correct values of the maximum intensity of thermal radiation and the angle at which the radiation source will be visible. Findings. Measurement algorithm of thermo radiation tension in the workplace has been developed. The system for modeling light was developed and tested. Cause significant of errors in repeated measurements of high heat fluxes was found. The new construction of the head receptionist for measuring radiant flux was proposed. This makes it possible to change the viewing angle from 5 ° to 140 ° and reduce material of devices. Systematic components associated with the similarity of the light pattern and the angular of orientation of the sensor were analyzed. Originality. Safe method of modeling parameters of the heating light microclimate has been proposed. Installing physical modeling irradiance has been improved. Improved design of the receiving head has been proposed. Practical value. The use of light simulation in the study of the thermal surge jobs allows to predict reliably the thermal irradiation on the surface of the object exposure.
