Abstract: Nusselt numbers are measured in three counterflow tube-in-shell heat exchangers with flow rates and temperatures representative of thermosyphon operation in solar water heating systems. Mixed ...

Abstract: Previous models for computer‐based design of rural natural gas networks produced layouts that were not totally consistent with objectives derived from field experience, namely “eliminate parallel piping,” “branch as early ...

Abstract: A model for layout and design of branched rural natural gas distribution systems is presented. The approach used in the model is based upon Dijkstra's and minimal spanning tree algorithms. These approaches are not, by ...

Abstract: We present the results of an experimental investigation into the behavior of a strongly advected jet (weak jet) in a coflowing ambient fluid. Laser-induced-fluorescence and image processing techniques are employed to provide ...

Abstract: Interaction between a jet and its neighbors in a still ambient fluid is dealt with. A model for the merging of an infinite line of equally spaced identical jets in a still ambient fluid is developed. The velocity and tracer ...

Abstract: An approach to facilitate the development and verification of a geographic information system for managing a water‐distribution network data base is proposed. The approach, which was developed for use in reliability analysis ...

Abstract: We present the results of an experimental investigation into the behavior of weakly advected jets in a cross-flow. Concentration profiles are measured using a laser-induced-fluorescence system. The data show that weakly ...

Abstract: The angular momentum principle is employed to locate the trajectories of wastewater plumes. This momentum-based method differs from the traditional approach where a perturbation analysis, based on the centerline velocities, ...

Abstract: We present a model for predicting the behavior of a buoyant discharge in a cross-flow. The model is developed through a hybrid of the length scale and integral approaches. We compare the predictions of the hybrid model ...

Abstract: A methodology for quantifying the variation in pipe failure rates associated with temporal and spatial clustering of water‐main failures is developed. In the first stage a cross‐referencing scheme is used to determine the ...
