- Abstract
- There is great need for a realistic and practical method of predicting interfacila mass and heat transfer rates in fluids when gradients of concentraiton and temperature are large. Recent theoretical developments, particularly in boundary layer theory, are increasingly specific and seem motivated by mathematical convenience rather than demands of the central problem. Moreover, there is a paucity of experimental data accurate enough to check any theory no matter how exact it may be. This report concerns a project in which the problem of large-gradient transfer was reviewed and redefined, experimental data were obtained in well-controlled systems, and return made to an earlier method of analysis which gains in physical generality what it loses in mathematical rigor.
