a proper verb that describe the formation of Taylor cone in polymer science

In polymer science, to form a core-shell nanofiber using electrospinning process, two separate solutions(i.e., core solution and shell solution) are injected to a capillary tube and ..... in order to form the core-shell structure, a regular Taylor cone is needed to be shaped which involves both solutions, and this is not feasible, unless the viscosity of the shell solution is high enough. Now, I do not know what is the proper verb that best describes mixing of both solutions, for example here: Ex: Therefore, the core solution could not "mix", "accommodate", "join", "solve" with the shell solution, and thus the core solution start dripping.
Which one is the most appropriate?? Accommodate, mix, join, solve,..........


Solution 1:

I simply googled formation of Taylor cone in polymer science and got this:

"...this causes dripping of the two solutions followed by an intermittent jet from the sheath with an occasional incorporation of the core."

I have no idea what a Taylor cone is but I suggest that this is a suitable way to discover the usual terminology. Another way is to use Google Scholar with a well-crafted search term.

Solution 2:

The core solution and shell solution are combined. They combine through contact and are coaxially ejected. (I don't believe they are actively mixed, so to speak of mixing would be somewhat misleading.)

If the two solutions don't suitably adhere or aren't effectively joined or if the less viscous core solution isn't successfully entrained with or attached to or integrated with or encapsulated by or supported by the more viscous shell solution, then the former might detach and drip.

(Note that these individual descriptions—a lack of adhesion, a lack of entrainment, a lack of encapsulation—describe different defect modes; select the one that best fits your intended meaning. Most broadly, you can say that they don't usefully combine.)

In that case, the shell solution, apparatus, and/or procedure cannot accommodate that particular core solution.
