Multicommodity Network Flows with Probabilistic Losses

Management Science, 1982
This paper considers the problem of maximizing the expected value of multicommodity flows in a network in which the arcs experience probabilistic loss rates. Consideration of probabilistic losses are relevant, particularly, in communication and transportation networks. An arc-chain formulation of the problem and an efficient algorithm for computing an

Flow With Losses

Journal of Engineering for Power, 1965
Even when one is willing to estimate the various loss coefficients in a given system, it is not always an easy matter to determine the flow rate and/or the total pressure drop across the system. Heretofore, a tedious trial-and-error approach (at the least) has been indicated, and this has often been based on a Darcy approximation which is questionable ...

Minor losses in oscillatory flow

The Journal of the Acoustical Society of America, 2001
Energy dissipation that is manifested by gradients in pressure in a flow system is often expressed in terms of a pressure loss factor of the form K=Δ2P/ρv2. While there is a wealth of data on loss factors for a myriad of geometries in steady flow, little such data exists for pulsatile or oscillatory flow.

Channel Routing with Flow Losses

Journal of Hydraulic Engineering, 1996
A technique is developed and implemented within the NWS FLDWAV model to account for the effect of flow-volume losses in one-dimensional (1D) open-channel unsteady flow modeling. A functional form for the loss-induced lateral outflow is derived based on a specified total-volume distribution along the reach in which the loss occurs.

Energy Loss in Dividing Flow

1992
Hydrodynamic phenomenon, occurring at the junction where a dividing flow is present, is extremely complex and greatly varies according to modifications in discharge conditions near the junction. This is a theoretical and experimental study of free surface dividing flow phenomena in rectangular, horizontal channels with particular attention to energy ...

Secondary Flows and Losses in Axial Flow Turbines

Journal of Engineering for Power, 1982
A simple approach to the estimation of angle variation and losses produced by the secondary flows near the hub and casing of a turbine is presented. The angle variation is predicted by ‘classical’ secondary flow theory, and the loss by estimating three components of the loss and adding them together.

A Note on Flow Regimes and Churning Loss Modelling

Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011
The purpose of this study is to investigate the various fluid flow regimes generated by a pinion running partly immersed in an oil bath and the corresponding churning power losses. In a series of papers, the authors have established several loss formulae whose validity depends on two different flow regimes characterized via a critical Reynolds number ...
