A comprehensive experimental evaluation was conducted on a single-cylinder, 4-stroke compression ignition engine. The baseline test utilized neat diesel with SAE 40 mineral oil, followed by tests using a 20 % blend of jojoba biodiesel. This blend was first tested with mineral oil, then with epoxidised jojoba oil as a bio-lubricant, and finally with a nano-enhanced bio-lubricant incorporating 2 % titanium dioxide (TiO₂) nanoparticles. Engine performance and emission characteristics were analyzed under varying load conditions to assess the viability of these alternatives. Parameters such as Brake Thermal Efficiency (BTE), Brake Specific Energy Consumption (BSEC), and Friction Power were evaluated. Emission outputs, including NOx, HC, CO<sub>2</sub> and smoke opacity, were measured using standard instrumentation. The results indicate that the use of jojoba biodiesel blends improves BTE and reduces BSEC, highlighting enhanced fuel conversion efficiency. The replacement of mineral oil with epoxidized jojoba oil as a lubricant resulted in lower frictional losses and improved thermal stability. The addition of TiO₂ nanoparticles further decreased BSEC, confirming enhanced energy efficiency and smoother engine operation. Emission levels were significantly reduced across all biodiesel-biobased lubricant combinations compared to the baseline. Overall, the study underscores the viability of jojoba oil-based fuels and lubricants as renewable and eco-friendly energy sources. These findings support the advancement of sustainable energy technologies in internal combustion engines, aligning with global efforts to reduce fossil fuel dependency and environmental impact.</div></div>","PeriodicalId":36341,"journal":{"name":"International Journal of Thermofluids","volume":"29 ","pages":"Article 101398"},"PeriodicalIF":0.0,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144912775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing studies often overlook the limitations of conventional heat transfer models, particularly when applied to repetitive pulsed laser exposure. This study addresses this gap by comparing the Bioheat and Dual-Phase Lag (DPL) models for predicting thermo-mechanical responses in multi-layered human skin. A validated one-dimensional computational framework was developed, incorporating light propagation, non-Fourier heat transfer, thermal damage via the Arrhenius model, and tissue deformation analysis. The model was rigorously validated against published data, demonstrating strong agreement with measured temperature profiles. Results indicate that repetitive pulsed laser irradiation generates sharper temperature gradients and higher transient thermal stress than continuous exposure, with the Bioheat model consistently overestimating surface temperatures (60.12 °C vs. 50.53 °C) and thermal damage, exceeding DPL predictions by up to three orders of magnitude. Likewise, Bioheat-based deformation and dermal stress were ∼0.4 mm (140%) and ∼0.29 MPa (126%) higher, respectively. These findings confirm that heat transfer assumptions critically influence temperature, damage, and mechanical predictions in laser-tissue interactions. Incorporating realistic models such as DPL is essential for optimizing laser protocols, improving treatment safety, and enhancing clinical outcomes in dermatology and biomedical applications.</div></div>","PeriodicalId":36341,"journal":{"name":"International Journal of Thermofluids","volume":"29 ","pages":"Article 101371"},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144908478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
