HEAT TRANSFER WITH PULSATING FLOW

Chemical Engineering Communications, 1980
This report concerns the frequency dependence of the heat transfer coefficient for water flowing in a tube. The investigation of this phenomenon was conducted in a double pipe heat exchanger in which the center stream was pulsed. The frequencies used ranged from 10 to 160 cycles per minute, and the average flow rates corresponded to a Reynolds number ...

Pulsating flow over a step

The Physics of Fluids, 1980
An experimental study has been made of air flow over a rearward facing step where the free-stream velocity has been perturbed by a sinusoidal fluctuation of 1 Hz. Velocities have been measured using a laser Doppler anemometer employing a gated photon correlation signal detection system.

Pulsating slurry flow in pipelines

Experiments in Fluids, 1989
An experimental study on pulsating turbulent flow of sand-water suspension was carried out. The objective was to investigate the effect of pulsating flow parameters, such as, frequency and amplitude on the critical velocity, the pressure drop per unit length of pipeline and hence the energy requirements for hydraulic transportation of a unit mass of ...

Simulation of pulsating channel flows

Russian Aeronautics (Iz VUZ), 2009
A method for simulating spatial-temporary characteristics of pulsating flows in the varying-in-length-area channels based on the solution of one-dimensional nonstationary equations of gas dynamics is presented. The calculation results are compared with the experimental data, and it is shown that the method being proposed rather adequately simulates ...

Pulsating Flow Hydraulic Concepts

SAE Technical Paper Series, 1965
<div class="htmlview paragraph">This paper will discuss an investigation that has been in process for over two years of the technical feasibility of the transmission of hydraulic power by the means of pulsating flow hydraulic concepts. A pulsating hydraulic system bears the same relationship to a continuous flow hydraulic system that an ...

Induced transport in pulsating flow

AIChE Journal, 1971
AbstractThe dispersion coefficient is evaluated in a general linear chromatographic system in which the velocity field is time periodic. Computations are carried out in detail for two examples. In the first example there are two phases and the flow pattern is simple. In the second example there is only one phase and the flow pattern is complex.

Orifice and Flow Coefficients in Pulsating Flow

Journal of Fluids Engineering, 1952
Abstract The flow equations pertaining to the behavior of a fluid passing through an orifice are set forth so as to relate the flow coefficient to the orifice configuration and to flow losses. The general nature of the flow coefficient is developed both for the case of instantaneous flow and pressure differences and for mean flow and ...

Pulsating flow in a pipe

Journal of Fluid Mechanics, 1985
Turbulent and laminar pulsating flows in a straight smooth pipe are compared at identical frequencies and Reynolds numbers. Most measurements were made at a mean Reynolds number of 4000, but the influence of Re was checked for 2900 < Re < 7500.

Internal Flow Induced Pulsation of Flexible Risers

Offshore Technology Conference, 2007
Abstract A Joint Industry Project, involving a number of operating companies and allied organisations (including ExxonMobil, BP, Statoil, the UK Health & Safety Executive, TNO and Bureau Veritas), is currently addressing the technical issues associated with high amplitude pressure pulsations generated by gas ...
