“…They conclude that the waterwheel would be operative for 124 days a year, with an additional 74 days if dams were used to regulate the channel. In a similar vein, the study of a historic watermill in Besalú (Catalonia) provides an estimation of its energy efficiency [5] which improves previous assumptions based on historical sources.…”

“…The subject of the majority of papers that describe fluid dynamic simulations in heritage is air motion (90% of the 60 or so papers reviewed in this article), most of which indoors (70%) and the rest outdoors (30%). The remaining papers deal with a diversity of topics, such as water movement in ancient hydrological structures [5,6].…”

This review addresses the use of computational fluid dynamics for the interpretation and preservation of heritage. Fluid dynamic simulations in the heritage field focus mostly on slow air movement in indoor spaces and they usually involve temperature and humidity. Simulations have different roles: they may be exploratory, they may be used to support preventive conservation and occasionally they aid historical or archaeological interpretation. The research questions rarely involve testing or development of new mathematical formulations; instead, existing computational models are used as a means to help solve practical issues. Computationally, the simulations are typically steady-state and they always use a turbulence model. Experimental validations against measured data are uncommon and there is a need for the production of benchmarking cases and the publication of experimental data. Further research is needed in order to explore suitable approximations to the simulation of change in the timescale of months or years, low turbulence flows for which current mainstream turbulence models are ill-suited, and new mathematical formulations for near-wall transport phenomena.

“…This leads to substantial improvements in the performance of some non‐equilibrium boundary layer regions 20. It also increases the code robustness since we found that some simulations carried out with the Star‐CCM+ program ended unexpectedly without any apparent error when the realizable k‐Ω turbulence model was used instead of the SST k‐Ω one (see, also, 21). For those runs that reached the stopping criteria, we did not find any relevant discrepancy between both turbulence closures (total torque variations lower than 0.1%).…”

In fluid mechanics courses of engineering curricula, theoretical performance curves of hydraulic turbines are obtained by means of simple analytical expressions that tend to overestimate experimental data. As we show here in the analysis of a laboratory-scale Pelton wheel, a much deeper physical insight can be achieved by means of general-purpose commercial computational fluid dynamics (CFD) software programs, becoming a suitable tool for academic activitiesThis work has been partially funded by the Generalitat de Catalunya under grant 2009-SGR-374, the MICINN under grant FIS-2009-13050, and the European Commission under grant NEST-28192-FEPR

Functional Analysis of Piedmont (Italy) Ancient Water Mills Aimed at Their Recovery or Reconversion

2019

Since ancient times and for hundreds of years, grain mills, hammers, sawmills, spinning mills, and hemp rollers have been powered by water wheels. In the nineteenth century there were hundreds of thousands of mills in all of Europe. It is an enormous historical and cultural heritage of inestimable value, which is for the most part, abandoned today. Recently, there is a renewed interest in their reuse, both for their widespread diffusion in the territory and for the excellent environmental integration and intrinsic sustainability. Even when, for economic reasons, their recovery for the original tasks is not suitable, the conversion into mini plants for the production of electricity can be advantageous. In the paper, analyzing some typical examples of the old water mill of the Piemonte region, in North-West of Italy, the mechanical architecture of old water mill, from water wheels to millstones, is described and the functional details of various mechanisms are provided. In fact, by knowing only the specifics of the ancient mills, it is possible to enhance their potential and restore them from the perspective of a renewed high quality production, or reconvert them in mini-plants for the production of electricity.
