Some results are validated by comparing with available other results. The effects of Res, Rep and \u03ba on the hydrodynamic properties of squirmer are discussed. The results show that there exist four distinct motion modes for the squirmer, i.e., horizontal mode, attractive oscillation mode, oscillation mode, and chaotic mode. Increasing Res causes the motion mode of the squirmer to change from a constant tumbling near the centerline to a stable horizontal mode, even an oscillatory or appealing oscillatory mode near the wall. Increasing the swimming intensity of squirmer under the definite Res will induce the squirmer to make periodic and stable motion at a specific distance from the wall. Increasing Rep will cause the squirmer to change from a stable swimming state to a spiral motion or continuous rotation. Increasing \u03ba will strengthen the wall\u2019s attraction to the squirmer. Increasing swimming intensity of squirmer will modify the strength and direction of the wall\u2019s attraction to the squirmer if \u03ba remains constant.<\/jats:p>","DOI":"10.3390\/e24070854","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T21:31:06Z","timestamp":1655933466000},"page":"854","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Hydrodynamic Behavior of Self-Propelled Particles in a Simple Shear Flow"],"prefix":"10.3390","volume":"24","author":[{"given":"Tingting","family":"Qi","sequence":"first","affiliation":[{"name":"State Key Laboratory of Fluid Power Transmission and Control, Zhejiang University, Hangzhou 310027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8418-1176","authenticated-orcid":false,"given":"Jianzhong","family":"Lin","sequence":"additional","affiliation":[{"name":"Laboratory of Impact and Safety Engineering of Ministry of Education, Ningbo University, Ningbo 315201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2481-0994","authenticated-orcid":false,"given":"Zhenyu","family":"Ouyang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Fluid Power Transmission and Control, Zhejiang University, Hangzhou 310027, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1093\/humupd\/dmi047","article-title":"Sperm transport in the female reproductive tract","volume":"12","author":"Suarez","year":"2006","journal-title":"Hum.
