“…However, a drawback of these models is the inability to predict the thermal response of piping to changes in the temperature of the fluid. An well-known option is to do CFD calculations for studying conjugate heat transfer in pipes [17]. We use them here not only as a sanity check for the heuristic approach but also to understand transient phenomena.…”

Accurate and responsive non-invasive temperature measurements are enablers for process monitoring and plant optimization use cases in the context of Industry 4.0. If their performance is proven for large classes of applications, such measurement principles can replace traditional invasive measurements. In this paper we describe a two-step model to estimate the process temperature from a pipe surface temperature measurement. This static case model is compared to and enhanced by computational fluid dynamic (CFD) calculations to predict transient situations. The predictions of the approach are validated by means of controlled experiments in a laboratory environment. The experimental results demonstrate the efficacy of the model, the responsiveness of the pipe surface temperature, and that state of the art industrial non-invasive sensors can achieve the performance of invasive thermowells. The non-invasive sensors are then used to demonstrate the performance of the model in industrial applications for cooling fluids and steam.

“…Reddy and Narasimham 50 performed numerical simulations to study combined conduction-convection in an enclosed annular region between inner heated rod and an outer cylinder for vast ranges of thermal conductivity ratios and presented thermal transfer correlations. Later, conjugate buoyant transport in a porous material placed in the annular region between two solid cylinders was numerically analyzed by Badruddin et al 51 Recently, John et al 52 made a detailed review on conjugate thermal transfer analysis covering various applied and theoretical aspects.…”

A vertical annular configuration with differently heated cylindrical surfaces and horizontal adiabatic boundaries is extensively studied due to many industrial applications. In this paper, we investigate the effects of conjugate buoyant heat transport within water based nanofluid with different nanoparticles such as alumina, titanium oxide or copper, which is contained in the gap of the enclosed annulus. The enclosed annulus is constituted by a thick inner cylinder with a constant high temperature, an exterior boundary with a constant low temperature and thermally insulated upper and lower surfaces. By investigating heat transport for broad spectrum of Rayleigh number, solid wall thickness, thermal conductivity ratio and nanoparticle volume fraction, we found that the influence of wall thickness on thermal dissipation rate along wall and interface greatly depend on conductivity ratio and vice-versa. In particular, we uncover that the choice of nanoparticle in a nanofluid and its concentration are key factors in enhancing the thermal transport along the interface. Specially, copper based nanofluids produces higher heat transport among other nanoparticles, and increasing nanoparticle concentration leads to enhanced thermal dissipation along interface. Our results are applicable to choose nanofluids along with other critical parameters for the desired heat transport.
