Abstract: This paper gives a brief synopsis of the thermo-dynamic imperative of the feedwater heater in the power cycle, followed by the development of two performance parameters. These two parameters, ...

Abstract: A computer-oriented method for axisymmetric stress analysis of integral tubesheet exchangers is developed. The tubesheet is modeled as a composite plate consisting of a perforated interior and a ...

Abstract: “Three element bolted joints,” consisting of an unstayed tubesheet sandwiched between two tapered hub flanges, find extensive use in U-tube type heat exchangers. A comprehensive analysis technique ...

Abstract: The edges of rollers in needle and roller bearings are crowned (i.e., rounded) in order to prevent large stress concentrations. At present, the crowning radius is determined empirically. In ...

Abstract: A method to determine the temperature field in a typical tubesheet ligament is developed. Using a numerical example, it is shown that, contrary to the common belief, a temperature gradient may ...

Abstract: In shell and tube heat exchangers, the triple segmental baffle arrangement has been infrequently used, even though the potential of this baffle system for high thermal effectiveness with low ...

Abstract: Minimizing solute carry-over into the product is the central object in the design of Radioactive Waste Concentration Systems. Two Stage Evaporators are intrinsically superior to single stage ...

Abstract: The unequal length change of the tubes in various tube passes of a multi-tube pass fixed or floating head tubular exchanger produces axial tube loads which may be substantial in some operating ...

Abstract: A simplified formula for predicting the change in bolt load from preload to operating condition in a ring-type bolted flange connection is presented. The results clearly demonstrate the important ...
