There are two uncommon examples to conclude. In all the situations considered, a gas or a liquid was moved and influenced by a penetrable structure, a PR that could be motionless or set in a motion itself by the medium. The droplet jet like that from a shower provides a situation when porous medium moves and induces a motion of the surrounding air, Fig. 1.17,A. A theoretical approach was suggested by Hunt [230] to consider droplets as a porous medium. A similar situation occurs when a bubble column arises from a source deeply in the sea or ocean, Fig. 1.17,B. Bubbles form a porous medium that induces the motion of the surrounding water. Of course, particular equations should be employed in each case, either for droplets or bubbles. The broadening of the jets can be explained in such models. Another approach to bubbles as to obstructions is suggested in the Chapter 7.

Where the site of a nuclear power plant requires consideration of the effects of an aircraft crash at or near the site, a fire hazard analysis of such an event should be made. It should be taken into account in this analysis that fires may occur at several locations because of the spreading of the aircraft s fuel. Smoke may also be produced at several locations. Spedal equipment such as foam generators and entrenching tools as well as specially trained on-site and off-site fire fighting personnel may be used to prevent such fires from penetrating structures containing items important to safety. (See Ref. [6], Section 2.)...
