TL;DR: In this article, a critical review on the mass transfer correlations under turbulent duct flow, as they appeared in the literature ( 1934-1984), and a discussion on the factors influencing mass transfer during membrane operations (reverse osmosis and ultrafiltration), like porosity and roughness of the membrane wall and change of viscosity and diffusion coefficient due to the strong concentration gradient.

TL;DR: A large number of methods to predict freezing and thawing times for foodstuffs have been proposed as discussed by the authors, and several attempts have been made to improve the original Plank equation by adding new terms and parameters, to make it suitable for the entire freezing process.

TL;DR: In this paper, the role of water in heat processing of solid foodstuffs is discussed, with special attention given to sorption isotherms and water diffusivity, and recent work in this field is referred to.

TL;DR: In this article, the concentration des aromes par pervaporation selon trois voies differentes is decrit, and a systeme modele is utilised, contenant 12 des principaux constituants du jus de pomme.
