Improved prediction of shell side heat transfer in horizontal evaporative shell and tube heat exchangers

This paper presents an improved prediction method for the heat transfer and pressure drop in the shell side of a horizontal shell and tube evaporator. The results from an experimental test program are used in which a wide range of evaporating two-phase shell side flow data was collected from a TEMA E-shell evaporator. The data are compared with shell side heat transfer coefficient and pressure drop models for homogeneous and stratified flow. The comparison suggests a deterioration in the heat transfer data at low mass fluxes consistent with a transition from homogeneous to stratified flow. The pressure drop data suggest a stratified flow across the full test range. A new model is presented that suggests the transition in the heat transfer data may be due to the extent of tube wetting in the upper tube bundle. The new model, which also takes into account the orientation of the shell side baffles, provides a vast improvement on the predictions of a homogenous type model. The new model would enable designers of shell side evaporators/reboilers to avoid operating conditions where poor heat transfer could be expected, and it would also enable changes in process conditions to be assessed for their implications on likely heat transfer performance.

Indiana Local Roads - An Asset Management Guide for Cities, Towns and Counties

This Guide is designed to serve as a resource to agencies adopting an asset management philosophy. It presents an asset management process that can be used by any local agency in Indiana. It also introduces common terminology and helpful hints to get you started. The Guide promotes a statewide approach to gather and analyze the information you need to develop an asset management plan. You can use this Guide to: learn more about what asset management is, identify the steps involved with implementing asset management, discover ways to use data to better communicate with elected officials, develop an effective asset management plan. The focus of this Guide is on Transportation Asset Management, but the same concepts can be applied to other assets that your agency manages, such as sewers and water treatment plants

Technical Review - PRS 87 Action Memo

These Technical Reviews refer to the Mound Laboratories in Miamisburg, Ohio, an Atomic Energy Commission facility for nuclear weapon research that would go on to close in 2006. The purpose of this document is to document and allow public comment on the propped Removal Action at PRS 87. This research was completed money allocated during Round 5 of the Citizens’ Monitoring and Technical Assessment Fund (MTA Fund). Clark University was named conservator of these works.

Technical Review - Building R, SW, 58, and 68 Slab Add 1

These Technical Reviews refer to the Mound Laboratories in Miamisburg, Ohio, an Atomic Energy Commission facility for nuclear weapon research that would go on to close in 2006. The purpose of this document is to notify the public of the addition of two Potential Release Sites (PRSs) PRS 253 and PRS 254 to the PRSs included in the Building R, SW, 58 and 68 Slab Action Memorandum. The two additional PRS are associated with the T-West Stack (PRS 253) and T-East Stack (PRS 254). Because these additional PRS are in the vicinity of the demolition and decontamination activities in the Building R and SW area, and because the Contaminants of Concern (COC) are the same as those outlined in the original Action Memorandum, incorporation of PRS 253 and 254 represents efficiencies in budget, manpower, and scheduling. This research was completed money allocated during Round 5 of the Citizens’ Monitoring and Technical Assessment Fund (MTA Fund). Clark University was named conservator of these works.
