This paper presents the control principle and method based on the equivalent throttling action of an aircraft arresting system and also presents the simulation of the arresting process by using this method.
Based on energy conservation theory and van der Waals's mixed rule, a mathematical model considering phase equilibrium with Peng-Robinson equation is deduced to describe gas flow through choke and temperature drop through choke.
Do the wind tunnel test (MianYang) for analyzing the feasibility of the multi-stage choke and kill system, and carry on the field experiment (KangCun-2 well), ensure the application effect on the multi-stage choke and kill system in practice.
In this paper, resonance conditions are put forward of two transfer functions for flow restriction in straight line, a set of calculating formulae are concluded of estimating resonance frequency, peak and phase difference, and the results calculated on these formulae are compared with that calculated on precise model. The error is within 5.5%, this shows that the estimating method in this paper is successful.
An investigation has been made in an aerodynamic shock tube, with M=8, of the diffuser starting with variable Reynolds numbers, and its throttle characteristics have been recorded.
This paper is devoted to the further investigation of diffuser operation with variable Reynolds numbers, and to determining the throttle characteristics, in particular, the total pressure reduction coefficient.
This corresponds to the presence in the exit section of the duct of a throttle or an impermeable barrier (in which case the flow rate is zero).
It should be noted that in this formulation the problem is of practical as well as theoretical interest, for example, in connection with the problem of designing throttle EHD converters .
Complete Navier-Stokes equations are solved numerically for the case of an intense swirling flow in an axisymmetric channel with an orifice plate in the delivery cross section and a throttle in the form of a peripheral slit at the opposite end.
The article considers inverse phenomena, with energy separation in a classical gas ejector, consisting in the fact that the cold and hot air zones change places, depending on the throttling conditions at the inlet and outlet of the ejector.
Fluctuations of the flow parameters of an incompressible viscous fluid in a collar-type flow throttling device
The flow in channels of the labyrinth seal type with one or two throttling stages is calculated on the interval of Reynolds numbers Re from 1.9·104 to 4.5·105.
Calculation of Filtration Throttling of Liquefied Gas with Evaporation
Conditions are determined under which convective heat transfer can be efficiently enhanced through artificially turbulizing the flow of coolant by means of periodical throttling, and the degree of this enhancement is evaluated.
A high-voltage switch of submicrosecond range based on an assembly of reverse switch-on dynistors (RSDs) connected in series and a coaxial saturable-core choke is described.
Dynistors are triggered using a control circuit in the form of a high-voltage magnetic-compression section, in which the current-forming capacitor is charged from the power-circuit capacitor using an additional low-power saturable-core choke.
Two types of sliding choke plungers have been proposed and tested.
Physical processes occurring upon turning-on of the transistor in a converter stage with a saturable-core choke, placed in the clamping diode's circuit, are analyzed.
It is shown that the use of the saturable-core choke can be expected to reduce the energy loss by half or more.
