Thread: que sufran

Quiero expresar lo siguiente en ingles:

Problemas interesantes asociados a la dinámica de estos fluidos son por un lado el desarrollo de una teoria asi como de herramientas numéricas y de simulación para la predicción del comportamiento de este tipo de fluidos, y por otro lado el estudio de las inestabilidades que sufran en su flujo, tanto en su interior como en su interfase.

Aqui esta mi intento, pero tengo dudas a partir de "... y por otro lado ...":

Interesting problems associated with the dynamics of these fluids are on the one hand the development of an analytical theory as well as a numerical and simulation description for the prediction of the behavior of this kind of fluids, and on the other hand the study of the instabilities that they suffer in its flow, both in its interior and in its interface.

Mi intento:

Interesting problems associated with the dynamics of these fluids are, on the one hand, the development of a theory as well as numerical tools (formulas?) and simulations for predicting the behavior of this kind of fluid, and on the other hand, the study of instabilities in the flow, both in the interior and at its interface.

Great contribution from an expert! However, I might make some remarks on the punctuation as follows,
"Interesting problems associated with the dynamics of these fluids are, on one hand, the development of an analytical theory and model for the prediction of their behavior; and, on the other hand, the study of instabilities in their flow, both within and at their outer interface."
