摘要： A method for operating a heater system including a resistive heating element having a material with a non-monotonic resistivity vs. temperature profile is provided. The method includes heating the resistive heating element to within a limited temperature range in which the resistive heating element exhibits a negative dR/dT characteristic, operating the resistive heating element within an operating temperature range that at least partially overlaps the limited temperature range, and determining a temperature of the resistive heating element such that the resistive heating element functions as both a heater and a temperature sensor. The resistive heating element can function as a temperature sensor in a temperature range between about 500° C. and about 800° C., and the non-monotonic resistivity vs. temperature profile for the material of the resistive heating element can have a local maximum and a local minimum.

摘要： A heating apparatus for an exhaust gas system, or a fluid flow system, is provided by the present disclosure. The heating apparatus has a container body and includes at least one heater element and a support member disposed inside the container body and configured for restricting movement of the at least one heater element in the container body. The support member defines a tortuous geometry and flanks opposed sides of the at least one insulated heater element along a majority of a length of the at least one insulated heater element, wherein the support member increases heat transfer from the at least one heater element to an exhaust gas flowing through the container body.

摘要： A heating apparatus for a fluid flow system having a fluid conduit includes at least one heater element and a support member within the conduit. The at least one heater element includes a resistance wire, a sheath, and an electrically insulating material. The sheath has a closed profile shape that extends along a tortuous path through the container body and surrounds the resistance wire along the tortuous path. The insulating material is disposed about the wire between the wire and the sheath. The support member restricts movement of the at least one heater element relative to the fluid conduit. The support member defines a corrugated geometry that follows the tortuous path while contacting the sheath along a majority of a length of the sheath. The support member increases heat transfer from the at least one heater element to a fluid flowing through the fluid conduit.

摘要： A method of predicting the temperature of a resistive heating element in a heating system is provided. The method includes obtaining resistance characteristics of resistive heating elements and compensating for variations in the resistance characteristics over a temperature regime. The resistance characteristics of the resistive heating element include, but are not limited to, inaccuracies in resistance measurements due to strain-induced resistance variations, variations in resistance due to the rate of cooling, shifts in power output due to exposure to temperature, resistance to temperature relationships, non-monotonic resistance to temperature relationships, system measurement errors, and combinations of resistance characteristics. The method includes interpreting and calibrating resistance characteristics based on a priori measurements and in situ measurements.

摘要： A susceptor for use in a heated fluid flow system is provided. In one form, a susceptor is arranged within a conduit and adapted to absorb radiant energy from at least one heating element and inhibit the radiant energy from being absorbed by the at least one wall of the conduit and/or other components. In another form, the susceptor absorbs and inhibits the radiant energy from being absorbed by the outer wall of the conduit.

摘要： A method includes providing thermal energy to a component, determining a thermal response of the component in response to providing the thermal energy, and determining a thermal characteristic of the component based on a reference thermal response and the thermal response. The method includes predicting a surface condition of the component based on the thermal characteristic and a predictive analytic model, where the predictive analytic model correlates the thermal characteristic of the component to an estimated surface condition of the component.
