Although all of the concepts evaluated significantly improved TVC performance, 

 the roughened tip proved, by far, to be the superior. Thus, continued work in this 

 area should first be directed to the roughened tip. In particular, the current 

 study should be exteneded to higher Reynolds numbers; and also, for scaling pur- 

 poses, cover a broader range of Reynolds number. In addition, the effects of rough- 

 ness on surface cavitation should be given close attention.
