Improvement of contact methods of heat flux measurement

A new method is proposed for determining local values of heat flux from jets of hot gases to a calorimetric probe of special form. Results are presented where this method is applied to an air plasma jet. For comparison, results obtained in the same conditions, using some other well-known methods are given. The paper examines the possibility of obtaining plasma parameters directly from heat flux values measured by unsteady calorimeters (sensor with a linear characteristic, or a dynamic thermocouple), located in a plasma jet
