Total impulse

The same solution presented in Fig. 14 can easily be recast (see Ref. 22) into another form, as in Fig. 15. Note here that the maximum scaled response curve is now essentially a rectangular hyperbola with one asymptote which depends only on the level of applied peak force and another asymptote which depends only on the level of applied total impulse. In the intermediate loading regime (the "knee" of the hyperbola), response determination requires knowledge of both peak force and total impulse. 

For many purposes, rather than using the total impulse I, it is more convenient to use an impulse per unit area per unit explosive weight, ie Ii = I/ca, or I = pGI/ca = p0I., (where pG is the density of the unexploded HE) which we shall call the impulse constant. The term I, has the dimensions of velocity and is closely related to specific impulse which is commonly used as a measure of effectiveness of propellant systems. 

Weakness of will, as traditionally conceived, is a problem of impulsive behaviour. It is clear, however, that impulsiveness is neither sufficient nor necessary for weakness of will. It is not sufficient, since the totally impulsive person, in whom there is no inner conflict, cannot be subject to weakness of will. That notion requires both that there is a conflict between two opposed wishes, and that the wish that the person himself judges to be the more decisive loses out. Nor does weakness of will always take the form of giving in to impulsive urges. As noted by Davidson (1980, p. 30), compulsive, rigid, rule-governed behaviour can also be a form of weakness of will, that is, acting against one s own... 

A widely-used model in this class is the direct-interaction with product repulsion (DIPR) model [173—175], which assumes that a generalised force produces a known total impulse between B and C. The final translational energy of the products is determined by the initial orientation of BC, the repulsive energy released into BC and the form of the repulsive force as the products separate. This latter can be obtained from experiment or may be assumed to take some simple form such as an exponential decay with distance. Another method is to calculate this distribution from the quasi-diatomic reflection approximation often used for photodissociation [176]. This is called the DIPR—DIP model ( distributed as in photodissociation ) and has given good agreement for the product translational and rotational energy distributions from the reactions of alkali atoms with methyl iodide.

The transient results can be summarized by examining the total impulse over one duty cycle for a single micro-nozzle firing. The results are shown in Fig. 6 also shown are the results from quasi-ID inviscid theory for comparison purposes. As expected, the total impulse from the simulations is less than that predicted by inviscid theory - this difference can be directly attributed to the integrated effect of viscous and geometric losses incurred during the transient process. The optimal angle for a linear micro-nozzle in the transient case is seen to be the same as for the steady-state operation.
