Relationship Between Dynamic Coefficients of Two Temperature Sensors Under Nonstationary Flow Conditions

A two-sensor correction method employs a relationship between the dynamic coefficients of the probes. This algebraic relationship is reduced to a proportion or a hyperbola and it depends on the sensors diameter ratio. It results from the application of fundamental equations governing the Nusselt number. This paper presents the analytical results of investigations on that relationship with particular use of the well-known experimental formulas governing the heat transfer between the gases and the pair of sensors.
