We consider an Einstein–Gauss–Bonnet massive gravity model in 4D AdS spacetime to obtain a possible black hole solution and discuss the horizon structure of this hole. The real roots vanishing metric function lead various types horizons. Furthermore, we derive thermodynamic quantities, thus insuring validity first law thermodynamics Smarr relation. quantities are modified presence parameter als...

many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...

We have used a simple ionic potential to simulate the melting of KCI pseudo-infinite crystal. Two MD simulations, one with constant Volume and the other with constant pressure condition are performed. These results are compared with the previous micro-sample simulation results. In the constant volume simulation the melting temperature increase substantially with increasing pressure. A method fo...

Reservoir fluids properties are very important in reservoir engineering computations such as material balance calculations, well testing analyses, reserve estimates, and numerical simulations. Isothermal oil compressibility is required fluid flow problems, extension of from values at the bubble point pressure to higher pressures interest calculations (Ramey, Spivey, McCain). a measure fractiona...

We study P − V criticality of black holes in Lovelock gravities in the context of horizon thermodynamics. The corresponding first law of horizon thermodynamics emerges as one of the Einstein–Lovelock equations and assumes the universal (independent of matter content) form δE = TδS − PδV , where P is identified with the total pressure of all matter in the spacetime (including a cosmological cons...

The study of rotary steering drilling technology is currently one of the hot topics in the drilling engineering field. It requires accurate well trajectory control instructions when rotary steerable tools are applied to achieve the well trajectory control goal. A drilling trajectory prediction model will benefit this progress. According to the continuous beam theory, a mechanical model of push-...

The long time behavior of an evaporating black hole presents a challenge to theoretical physics and touches relevant conceptual issues of quantum gravity, such as the information paradox. There are basically two strategies: top-down, i.e., to construct first a full quantum theory of gravity and to discuss black hole evaporation as a particular application thereof, and bottom-up, i.e., to sidest...
