Numerical Investigation for Convective based Transient Heat Flux on The Stagnation Point of the Spherical Nose by K and E Type of Coaxial Thermocouple
Abstract
Transient measurement of surface heating rates is a very important activity for short duration in the many
applications in the area of the aerodynamic surface, internal combustion engines, for testing wind tunnel model in impulse
facilities etc. The surface heating rate is generally measured from temperature by using calorimetric gauges (like coaxial
surface thermocouple and thin film gauge sensor) on the surfaces of aerodynamic application. Coaxial thermocouple can be
measured suitably of highly surface heat fluxes due to the response time of this type of sensors are very less (1μs). This type
of reusable thermocouple fabricated easily in the house and thus it’s cost effective. By using a proper one-dimensional heat
conduction modeling, the surface heat fluxes are estimated from the measured histories of temperature. The purpose of this
work is to numerical investigating of transient heat flux on the stagnation point of the spherical nose by using K and E type
thermocouple.
