In this study, a general theoretical solution was established using Fourier transform, but \u03c6(t) was not directly present in the transformation processes, and \u03c6(t) was substituted into the general theoretical solution to obtain the corresponding analytical solution. Additionally, the specific solutions and corresponding mathematical meanings were discussed. Moreover, numerical verification and sensitivity analysis were applied to the proposed model. The results showed that T(x,t) was directly proportional to the thermal diffusivity (a) and was inversely proportional to calculation distance (x) and the coefficient of cooling ratio (\u03bb). The analytical solution was more sensitive to the thermal diffusivity than other factors, and the highest relative error between numerical and analytical solutions was roughly 4% under the condition of 2a and \u03bb. Furthermore, T(x,t) grew nonlinearly as the material\u2019s thermal diffusivity or cooling ratio coefficient changed. Finally, the analytical solution was applied for parameter calculation and verification in a case study, providing the reference basis for numerical calculation under specific complex boundaries, especially for the study of related problems in the fields of fluid dynamics and peridynamics with the heat-conduction equation.<\/jats:p>","DOI":"10.3390\/axioms12010061","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T04:51:31Z","timestamp":1672894291000},"page":"61","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Analytical Solution to the One-Dimensional Unsteady Temperature Field near the Newtonian Cooling Boundary"],"prefix":"10.3390","volume":"12","author":[{"given":"Honglei","family":"Ren","sequence":"first","affiliation":[{"name":"College of Civil Engineering, Hefei University of Technology, Hefei 230009, China"}]},{"given":"Yuezan","family":"Tao","sequence":"additional","affiliation":[{"name":"College of Civil Engineering, Hefei University of Technology, Hefei 230009, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2210-4877","authenticated-orcid":false,"given":"Ting","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Civil Engineering, Hefei University of Technology, Hefei 230009, China"}]},{"given":"Bo","family":"Kang","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Hefei University of Technology, Hefei 230009, China"}]},{"given":"Yucheng","family":"Li","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5832-1128","authenticated-orcid":false,"given":"Fei","family":"Lin","sequence":"additional","affiliation":[{"name":"College of Civil Engineering, Hefei University of Technology, Hefei 230009, China"},{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,5]]},"reference":[{"key":"ref_1","unstructured":"Fourier, J.B.J.
