The overall heat transfer coefficient, hov, depends mainly on the flow rates of the reacting and the cooling fluid, the physical properties of the fluids, and the material of construction of the MSR [28,29]. To avoid pronounced temperature profiles, a minimum ratio of reaction time to cooling...
where k is the rate constant or rate coefficient for the reaction, CA is the concentration of reactant A, and CB is the concentration of reactant B. By definition, the rate constant is independent of the concentrations of the reacting species but is dependent on other variables that influence...
prediction reliability is also quite high, but it varies irregularly with the rate coefficient of the reverse reaction \(f\), see Figs. 5 and S5. Stochastic variation in the success rates is an inherent feature of the deep-learning algorithm: the training set (see Supplementary Table S1...
In particular, the mean reaction time is the sum of two time scales corresponding to the inverse diffusion coefficient and the inverse intrinsic reactivity (see Eq. (5)), such that the influence of diffusion control and (chemical) rate control are separable13. For many biochemical reactions, ...
Problem DefinitionThe material balance along the length of the reactor is at steady state for a flat velocity profile. A first-order irreversible reaction is formulated as follows:(1) where D denotes the dispersion coefficient, U is the flow velocity, k is the rate constant for the reaction,...
