The same
polytrophic evolution that has been selected for the pipe flow model (this evolution is intermedium between an isothermal law and an isentropic law) has been assumed in Equation 11 for evaluating the bulk modulus of elasticity (E) according to the analytical expressions reported in [33, 20].
Where V is the instantaneous cylinder volume and is the
polytrophic constant.
If the accumulator is loaded or unloaded rapidly, the thermodynamic process of the gas state change belongs to an adiabatic process and the value of the
polytrophic exponent is n = 1.4.
Parameter
polytrophic head exponent is defined as[5]:
They are nonlinear ordinary differential equations which describe the equilibrium density distribution in self-gravitating sphere of
polytrophic isothermal gas and have a singularity at the origin [1].
Cyanobacteria associations in shallow
polytrophic lakes: influence of environmental factors.
Other LMC Hymenoptera may live relatively longer lives, are synovigenic, the adults have
polytrophic ovaries and feed on sugary substances, as well as internal fluids (haemolymph) of their hosts, e.g., Nasonia vitripennis (Walker); (Werren 1980, Simbolotti et al.
Females typically have three spermathecae and
polytrophic ovarioles (Dodson 1978; Fritz & Turner 2002); ovaries may contain more than one flush of mature eggs at a time.
Phosphorus balance of a
polytrophic shallow lake with the consideration of phosphorus release.
Because crawfish are
polytrophic and consume significant quantities of invertebrates and seeds as well as detritus (Momot 1995), all water birds feeding in crawfish ponds compete with the crawfish for food.
On the broad nutritional requirements of the mud snail, Ilyanassa (Nassarius) obsoleta (Say), and its
polytrophic role in the food web.
where C and [C.sub.2] are constants whose values are 0.12 and 0.001, [c.sub.m] is the mean piston speed, [c.sub.u] is the instantaneous tangential velocity of the gas in the chamber that was adjusted using CFD calculations, [p.sub.0] is the pressure during motoring conditions assuming a
polytrophic evolution, and finally [C.sub.W1] and [C.sub.W2] are constants, whose values are adjusted for each engine by means of a combination of experimental and modelling methodology.
