tailieunhanh - Transport phenomena (Sencond edition)

Each of the exciting new technologies blossoming around us is governed, at the detailed level of interest, by the conservation laws and flux expressions, together with information on the transport coefficients. Adapting the problem formulations and solution techniques for these new areas will undoubtedly keep engineers busy for a long time, and we can only hope that we have provided a useful base from which to start. | ALGEBRAIC OPERATIONS FOR VECTORS AND l TENSORS IN CARTESIAN COORDINATES s is a scalar v and w are vectors T is a tensor dot or cross operations enclosed within parentheses are scalars those enclosed in brackets are vectors Note The above operations may be generalized to cylindrical coordinates by replacing x y z by r 6 z and to spherical coordinates by replacing x y z by r 6 4 .
