A continuum description in the form of a nonlinear diffusion equation is derived systematically in the dilute limit using the method of matched asymptotic expansions. Numerical simulations are performed to compare the results of the model with those of the commonly used mean-field and Kirkwood-superposition approximations, as well as with Monte Carlo simulation of the stochastic particle system, for various interaction potentials. Our approach works best for very repulsive short-range potentials, while the mean-field approximation is suitable for long-range interactions. The Kirkwood-superposition approximation provides an accurate description for both short- and long-range potentials but is considerably more computationally intensive.<\/jats:p>","DOI":"10.1137\/17m1118543","type":"journal-article","created":{"date-parts":[[2017,12,21]],"date-time":"2017-12-21T11:48:48Z","timestamp":1513856928000},"page":"2294-2316","source":"Crossref","is-referenced-by-count":18,"title":["Diffusion of Particles with Short-Range Interactions"],"prefix":"10.1137","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7829-5652","authenticated-orcid":true,"given":"Maria","family":"Bruna","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
