These bubbles are assumed to be spherical and non-permeable with the non-Newtonian fluid, viz. the couple stress fluid filling their interior. Further, the bubbles are presumed to be static in the flow domain, where a Newtonian fluid streams past these bubbles with a constant velocity (U) along the negative x-direction. We developed a mathematical model in the bipolar coordinate system for the fluid flow outside the bubbles and the spherical coordinate system inside the bubbles to derive a separable solution for their respective governing equations. Furthermore, to evaluate the model's applicabilities on the industrial front, the data on some widely used industrial fluids are given as inputs to the model, such as density, the viscosity of air or water for the fluid flow model developed for the region outside the fluid bubbles and the data on Cyclopentane or DIDP (non-Newtonian) for that within the bubbles. Some interesting findings are: the pressure in the outer region of the bubbles is higher when filled with low viscous industrial fluid, Cyclopentane, than a high viscous fluid, DIDP. Furthermore, an increase in the viscosity of Cyclopentane did not alter the pressure distribution in the region outside the bubbles. However, there is a considerable effect on this pressure in the case of DIDP bubbles.</jats:p></jats:abstract><publication_date media_type="online"><month>4</month><day>15</day><year>2021</year></publication_date><publication_date media_type="print"><month>4</month><day>15</day><year>2021</year></publication_date><pages><first_page>79</first_page><last_page>91</last_page></pages><ai:program xmlns:ai="http://www.crossref.org/AccessIndicators.xsd" name="AccessIndicators"><ai:free_to_read start_date="2021-04-15"/><ai:license_ref applies_to="am" start_date="2021-04-15">https://www.wseas.org/multimedia/journals/fluid/2021/a185113-004(2021).pdf</ai:license_ref></ai:program><archive_locations><archive name="Portico"/></archive_locations><doi_data><doi>10.37394/232013.2021.16.8</doi><resource>https://www.wseas.org/multimedia/journals/fluid/2021/a185113-004(2021).pdf</resource></doi_data><citation_list><citation key="ref0"><unstructured_citation>Rybczynski W.
