THE EXPERIMENTAL STAND FOR A RESEARCH OF THERMAL AND AERODYNAMIC PROCESSES OF MIXED CONVECTION HEAT EXCHANGE FOR ROUND-FUNED PIPES AND BUNCHES
The experimental stand for a research of the free and mixed convection consisting of a box, a heat exchange bunch, the control instrumentation, the exhaust mine is developed. Testing experiments on a thermolysis for calorimetric pipes with various degrees of blackness are made. The comparative analysis of compliance of the speed of air measured in the different ways through compliance of mass expenses is made. It is established that osculum and leak of air on length of the exhaust mine are absent and also the created experimental installation allows to perform reliable measurements of temperature and speed of a stream of the cooling air. The error of skilled data is defined.
