Applications of integral averaging to momentum transfer
In the context of discussing approximations in Sec. 3.1.2, I mentioned that not every interesting problem should be attacked by attempting to find a simultaneous solution to the equation of continuity, Cauchy’s first law, the jump mass balance, and the jump momentum balance. Some problems are really too difficult to be solved in this manner. In other cases, the amount of effort required for such a solution is not justified, when the end purpose for which the solution is being developed is taken into account.
