A method for monitoring a surface condition of a component includes providing thermal energy to a component, determining a thermal response of the heater 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 the 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.

A method of detecting accumulation of material deposits within a fluid flow conduit includes providing, by a controller, an excitation signal to a heating element of the fluid flow conduit. The method includes obtaining, by the controller, thermodynamic data of the fluid flow conduit in response to providing the excitation signal, where the thermodynamic data includes heat flux data, diffusivity data, time data, temperature differential data, or a combination thereof. The method includes determining, by the controller, an amount of material deposits based on the thermodynamic data.
