Simultaneous Mass Transfer and Chemical Reactions in Engineering Science: Solution Methods and Chemical Engineering Applications illustrates how mathematical analyses, statistics, numerical analysis and computer programming can summarize simultaneous mass transfer and chemical reactions in engineering science for use in solving problems in quantitative Chemical and Biochemical Engineering design and analysis. The book provides statistical methodologies and R recipes for advective and diffusive problems in various geometrical configurations. The R-package ReacTran is used to showcase transport models in aquatic systems (rivers, lakes, oceans), porous media (floc aggregates, sediments, ...) and even idealized organisms (spherical cells, cylindrical worms, ...).
