One option is to pass a hidden form field that you update to specify the number of dynamic fields (i.e. "3"). When you submit the form, you know there are 3 fields so you can loop from 1 to 3 (or whatever number you pass as the total count) and reference each of them by name and number.
You can also use form.fieldList to get a list of all the form fields that were submitted, and determine how many dynamic fields there are that way.
Or, you can use something like my Form Utilities CFC which lets you name the fields with an array syntax (i.e. "myField" and have CF automatically convert it into an array that you can then loop over.
