Volume aging rule

Volume Aging Rule Linear Aging Rate x Area... 

Another Lagrangian-based description of micromixing is provided by multienvironment models. In these models, the well macromixed reactor is broken up into sub-grid-scale environments with uniform concentrations. A four-environment model is shown in Fig. 5.16. In this model, environment 1 contains unmixed fluid from feed stream 1 environments 2 and 3 contain partially mixed fluid and environment 4 contains unmixed fluid from feed stream 2. The user must specify the relative volume of each environment (possibly as a function of age), and the exchange rates between environments. While some qualitative arguments have been put forward to fit these parameters based on fluid dynamics and/or flow visualization, one has little confidence in the general applicability of these rules when applied to scale up or scale down, or to complex reactor geometries. 

TBVM is a completely different product, made of cooked must and aged in series of decreasing volume casks made of different wood for at least 12 years and up to 25 years or longer. TBVM is a high quality product, whose production is ruled by law (Italian D.M., February 9, 1987) and its cost on the market is rather high dependent upon its ageing process.
