The developed method uses the same principle as a hot wire anemometer, where the velocity perpendicular to an optical fiber is estimated as a function of the cooling curve of a gold-coated layer on the optical fiber Joule-heated intermittently. The developed optical fiber sensor demonstrated the ability to acquire a transient velocity profile in airflow experiments with high repeatability and accuracy. This paper describes optical fiber-based velocity measurement in the velocity range of approximately 0\u20137 m\/s with an error of approximately 10% compared to a hot wire anemometer and a new method for simultaneous temperature and velocity measurements. Applicability to velocity distribution measurements and seconds transient velocity changes are also described.<\/jats:p>","DOI":"10.3390\/s23031627","type":"journal-article","created":{"date-parts":[[2023,2,2]],"date-time":"2023-02-02T01:53:54Z","timestamp":1675302834000},"page":"1627","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Development of Measurement Method for Temperature and Velocity Field with Optical Fiber Sensor"],"prefix":"10.3390","volume":"23","author":[{"given":"Masashi","family":"Sekine","sequence":"first","affiliation":[{"name":"Nuclear Regulation Authority, 1-9-9 Roppongi, Minato-ku, Tokyo 106-8450, Japan"},{"name":"Faculty of Science and Engineering, Waseda University, 3-4-1 Okubo, Shinjuku-ku, Tokyo 169-8555, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1221-2874","authenticated-orcid":false,"given":"Masahiro","family":"Furuya","sequence":"additional","affiliation":[{"name":"Faculty of Science and Engineering, Waseda University, 3-4-1 Okubo, Shinjuku-ku, Tokyo 169-8555, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,2]]},"reference":[{"key":"ref_1","first-page":"330","article-title":"Full-Scale Measurements of Indoor Environmental Conditions and Natural Ventilation in a Large Semi-enclosed Stadium: Possibilities and Limitations for CFD Validation","volume":"104\u2013106","author":"Blocken","year":"2012","journal-title":"J.
