A Noahide woman does not have a recurring interval of "Niddah" days (a commanded period of separation from her Gentile husband), so there is no reason for her to perform a Jewish-style ritual immersion. Doing so would be like creating a new commandment for herself, because of its ritual nature which has no practical purpose for Gentiles. If a Gentile couple decides to refrain from relations during the days of the wife's menstrual flow (and they are permitted to voluntarily take on that restriction, because it has positive benefits for the marriage relationship), then she can perform some activity to mark the end of that period of time and their return to having relations. For example, this could be taking a bath or a shower, or just the return to sleeping together if they had separated from doing so during those days.
