Study on usage of Elzaki transform for the ordinary differential equations with non-constant ‎coefficients

Although Elzaki transform is stronger than Sumudu and Laplace transforms to solve the ordinary differential equations withnon-constant coefficients, but this method does not lead to finding the answer of some differential equations. In this paper, a method is introduced to find that a differential equation by Elzaki transform can be ‎solved?‎

Experimental Modeling of a Long Orifice-type Restrictor of High Speed Turbine Hybrid Bearing

To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of ...

PIV Study of Conical Forebody Flow Control Using Plasma Actuators

Duty cycle modulation of the alternate blowing from two opposite facing plasma actuators on the leeward surface near the apex of a cone having semi-apex angle of 10° to control the mean lateral force, moment and the flow control mechanisms are presented. The pressure distributions over the cone forebody are measured using steady pressure-tappings. The flowfields are visualized by a two-dimensio...

2+1 Black Hole with a Dynamical Conical Singularity

We find black hole solutions to Euclidean 2+1 gravity coupled to a relativistic particle which have a dynamical conical singularity at the horizon. These solutions violate the standard area law for black hole entropy, their entropy being proportional to the total opening angle. Since each solution depends on the number of windings of the particle path around the horizon, the significance of the...
