What reading level is On Jets Produced By Conical Nozzles book?
To quickly assess the difficulty of the text, read a short excerpt:
:vWj #J -.
tf^'i - 22 - (15) mR R + sR + (2^ - ST' )R^ + q' = 0.
It is Immediately verified that R = R is a solution of '' o (15) and we shall now show that any solution of (15) v;hich gets close to R performs damped oscillations about R, In a t_ interval where R(t) is monotonic, a unique inverse t(R) is defined. Introducing u(R) defined by (16) u(R) = R(t(R)) one gets from (15) a first order equation for u.
(17) u' = - + su + ( m' ST' )u' mu The point R=R, u=0 is a singular point of this equat...ion, and an easy verification shows that it is, pro- vided that assumption (lU-) holds, a vortex point. Con- sequently, the solutions of (1?) near R = R, u = spiral about this point, see fig. 5» The reinterpretation of this "phase space" diagram in the "physical space" leads to damped oscillatory motion.
locus u'=0 u'0 Fip;ure 5 Since R satisfies a non-linear equation, its "period" (time elapsed between two successive maxima) and its "half time" depend on initial data. One obtains an estimate of - 25 - the period and the half time by assuming a motion of small amplitude and linearizing the differential equation.
