isentropic

Convection might not be present but vertical motion can still occur from orography and complex mechanisms such as isentropic lift.

The turbocharger model uses tabulated performance maps which are interpolated during the simulation to evaluate the mass flow rate and isentropic efficiency.

This process is reversible or in other words isentropic. On Fig.

Viewing this quantity on the 355-K isentropic surface, we found that during their intensification stage, each of the four storms had an unusually symmetric "doughnut" structure to the PV field.

The isentropic efficiency of the compressor was taken as 0.7.

The total-to-total isentropic efficiency curves (Figure 10(b)) follow practically the same trend at low mass flow rates but deviate slightly at high mass flow rates except for the configuration rotor 2 : 3 which the efficiency undulates at near choking, since the scaling affected the losses.

In [13], Yang and Wang considered the formation of delta shock waves and the vacuum states in the solutions of the homogeneous isentropic Euler equations for modified Chaplygin gas when the pressure vanishes.

A further assumption is that the flow of the two-phase mixture is isentropic (i.e., at any point the sum of entropies of liquid water and vapor remains equal to the entropy in the initial all-liquid state corresponding to saturated conditions at the initial water pressure).

Suppose that sound propagation is an isentropic process, for which [v.sup.2.sub.s] = [partial derivative]p/[partial derivative][rho] = [B.sub.A]/[rho]; bulk modulus [B.sub.A] = [rho][v.sup.2.sub.s] is reciprocal to the acoustic compliance from (2) and can be expressed as follows:

In this paper, our studies and analyses focus on characteristics of isentropic (iso-[theta]e) processes based on PLAM index; the height of pollution mixing layer features and the vertical atmospheric structure are analyzed; the correlation of the PLAM sensitive parameter-condensation function ([f.sub.c]) with the height of pollution mixing layer is discussed; correlation and interactions of PLAM index with local aerosol density variations are both explored; and the mechanism for forming the heavy pollution or severe hazy weather event in December 2016 is also addressed.
