With the largest enrollment of two hundred so far in the six years, the workshop is attended at two week intervals by students who will work on their high schord publications. The workshop is directed by Prof. Wesley H. Maurer of the journalism department, while Prof. John Field acts as assistant chair- man and coordinates workshop ac- tivities. Workshop Instructors Assisting in the workshop's year- book division is Matti Crump, ad- visor to student publications in Arthur Hill High School, Saginaw and Robert Beauchamp, chairman of the department of English and department of publications, Pon- tiac Senior High School, works with the newspaper section. The major emphasis in the news- paper division is directed toward maturity in publications, designed to broaden backgrounds and better insight into newspaper problems. Each two-week group works and puts together their own newspaper whereby the various members of the workshop follow-up assign- ments, write headlines, make up dummy pages and write editorials. Yearbook Emphasis The emphasis in the yearbook section of the workshop is on con- tent and development of theme and design. They work to prepare attractive, readable copy with makeup and pictures playing im- portant roles. These high school students who attend the workshop come from the states surrounding the Great Lakes and many of them are spon- sored by commercial newspapers. The workshoppers live in the dorms on campus and follow a busy schedule which is mapped out for them by their instructors which includes a tour of the cam- pus, lectures, special group assign- ments and the regular workshop lab sessions. Detailed wind tunnel models of industrial power plants have been used by a University civil engineer since 1935 to combat air pollution. He is Prof. Robert H. Sherlock, who begins his retirement furlough this summer after pioneering in the use of models to study the ways industrial gases behave after being introduced into the atmos- phere. From his research have come scores of reports, technical articles and practical suggestions as to how power plant smoke stacks should be designed or altered to avoid blanketing nearby areas with downwashing gases. Set up Models To reach these conclusions, Prof. Sherlock and his associates set up models of the plants under study and their surroundings in the test section of a low-speed University wind tunnel. The tunnel's eight-bladed pro- peller then sucks air past the model as smoke ejection speed and other factors are varied, the researchers take hundreds of photographs to record whether the smoke escapes in a stable plume or is carried to the ground beyond by turbulent air currents. If the plume remains undis- turbed for several thousand feet beyond the plant, it generally will be safely absorbed, Professor Sherlock points out. ~1 I WIND TUNNEL MODEL-University mechanical engineer Frederick Boutwell adds a smokestack to model of a Long Island, N. Y. power plant whose design is being tested in a University wind tunnel. Researchers can tell how smoke from real stacks will behave. "The atmosphre has great capacity to disperse contaminants provided they are introduced prop- erly," he notes. "It is when the gases cannot be forced high enough to escape local turbulence caused by the tension, buildings or the stack itself that trouble DUMMY MAKEUP-Bob Beauchamp explains the intricasies of making up a page to his workshop students, --CAMPUS-. 211 S.

Gases Out of Reach In most cases, an increase in stack height or ejection velocity carries the gases out of the reach of turbulence, Prof. Sherlock says. In other situations, it is necessary to change the shape of the plant or nearby structures so as to elimi- nate the turbulence itself. He recalls that stack height at one plant could not be increased becauses it was near the end of an airport runway. After a wind tunnel study, he suggested "streamlining" the building by ter- racing a high, unbroken wall which deflected winds upward in trouble- some currents. This was done, and the situation alleviated. The most striking example of the use of stack height to elimi- nate downwash is at Clifty Creek, Ind., where the stacks of a power station have been built 682 feet high at Prof. Sherlock's suggestion. They are the tallest in the world, and their gases will clear heavily populated hills on the north bank of the Ohio River. Most stacks are less than 250 feet high. Work Complicated Prof. Sherlock's work is compli- catedby the fact that most plants are located along rivers or lake', for the hills that are generally , close by create air turbulence, Because of the aerodynamic and meteorological factors involved Prof. Sherlock also draws upon University experts in those field for assistance. The volume of his work, con- tracted through the University's Engineering Research Institute, has increasesd sharply in recent years as companies seek volun- 4 tarily to control downwash at a time of growing public interest in air pollution. He accepts only those projects which present a challenging research problem. His studies of the effects of wind in power lines and poles from 1927T to 1934 led to his entry into the air pollution field. A Chicago power plant that was emitting four, million cubic feet of gas every minute heard of his work, and turned to him for help. An exten- 4 sive field survey convinced him it would be easier to reproduce the plant in a wind tunnel for study. From this model came recommen- dations that eliminated all cases of downwash, and his career Was launched. ...................... I U STUDENTS!
