The dispersion of nanomaterials in everyday liquids is becoming a major focus of nanotechnology. Dispersing nanoparticles in a conventional liquid increases its thermal conductivity, which is useful for both generating and transferring energy. The primary focus of this study has been on energy transportation. Thermal radiations and Soret implications were used in this investigation. The Soret impacts are also taken into account. Here, the numerical research is based on the Buongiorno model. Using suitable similarity conversions, the flow mathematical equations are converted into the nonlinear ordinary differential equations. This study makes use of the popular numerical bvp4c method. Graphs and tables are used to illustrate the physical quantities, which include a number of impacts that are caused by the constraints of the component. The key findings are that high magnetic field factor, thermophoresis factor, Brownian motion factor, and radiation factor cause high-temperature distribution. Moreover, thermophoresis and Brownian motion factors are responsible for enhancing the variation of Nusselt and Sherwood numbers. The growth in Nusselt number is controlled by the material factor, Lewis number, radiation factor, Soret number, and inclination angle. The presence of thermophoresis parameter, radiation factor, and inclination angle generate growth in Sherwood number.</p>\u0000 </div>","PeriodicalId":44939,"journal":{"name":"Heat Transfer","volume":"54 3","pages":"2393-2406"},"PeriodicalIF":2.8,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801729","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}

By integrating modified osprey optimization, the SA-OSNN approach enhances thermal management by dynamically adjusting model parameters in response to changing environmental conditions, ensuring efficient and effective thermal control. This method is used as an optimization tool that works in conjunction with established thermal management solutions, such as GaN, SiC, and AlN materials, which provide the physical properties necessary for effective heat dissipation.

A flexible thin heater positioned at the center of the cavity serves as the heat source, while the moving side walls maintained at constant low temperature perform as a heat sink. The numerical approach adopts the finite element Galerkin method, integrating the Arbitrary Lagrangian–Eulerian framework with moving mesh technique to solve the associated flow, thermal, and stress fields. The thermoelastodynamic system behavior is analyzed through streamline, isothermal, and heater deformation visualizations, along with an evaluation of heat transfer performance, namely, the average Nusselt number. FSI-induced internal stress scenario in the heater is also studied in terms of maximum von Mises stress. Variation of system conditions necessarily includes mixed convection strength, shearing effect, fluid rheology, and flexibility of the heater manifested by four governing system parameters, namely, the Richardson number (0.1 ≤ <i>Ri</i> ≤ 10), Reynolds number (100 ≤ <i>Re</i> ≤ 300), power-law index (0.6 ≤ <i>n</i> ≤ 1.4), and Cauchy number (10⁻⁴ ≤ <i>Ca</i> ≤ 10⁻⁸). The findings of this study reveal a significant improvement in heat transfer for shear-thinning fluids, with the most notable enhancement occurring at the highest Richardson number (<i>Ri</i>), where the heat transfer rate shows an increase of up to 33.33% compared with Newtonian fluids.

Velocity decreases with increasing permeability (K), Schmidt number (Sc), radiation (R), and magnetic field strength (M).

This study uses a bioheat transfer model to develop a comparative analogy to differentiate burn intensity from hot dishes, hot fluids, radiation, and flash fires, aiming to differentiate the burn profiles of each incident type. The finite element method is employed to solve the time-dependent Pennes' bioheat transport equation concerning the three distinct layers of human skin. The Arrhenius equation is implemented to quantify the damage fraction associated with thermal burns. The burn intensities for the degrees of burns (first, second, and third) are evaluated by applying Henriques burn integral, considering various burning conditions and the corresponding exposure times required for each burn. The numerical results are displayed in various formats, including volume temperature plots and line graphs of damage fraction. The findings reveal that first-degree burns occur the fastest, followed by second-degree burns, with third-degree burns taking the longest to develop. Notably, burns from direct contact with a hot dish are more severe than those from freely flowing heated fluids. The results highlight that exposure time, temperature, and thermal conductivity are key factors in burn depth and tissue damage, offering valuable insights for burn treatment and risk management.

We employ the sophisticated peristaltic wave approach to construct a model that exhibits nonuniform boundaries characterized by diverse amplitudes and phases. We focus on how the walls adjust to the convective boundary conditions. To simplify the system, we used the lubrication method and the Debye–Huckel linearization technique to linearize the Poisson–Boltzmann equations. The electroosmotic parameter and the Helmholtz–Smoluchowski velocity contribute to the rise in fluid velocity. The fluid's temperature drops and its concentration rises when the joule heating parameter is raised. The temperature and concentration of the fluid showed similar patterns concerning the Biot numbers. When the reaction mechanism parameter values increase, the fluid concentration decreases because the diffusivity of the chemical molecules decreases. The Nusselt number (Nu) increases in the center of the channel as a result of the joule heating parameter. The current research on electrokinetic fluid flow through microchannels and micro-peristaltic transport has sparked immense interest in biomedical engineering. In particular, electroosmosis shows great potential in enhancing different aspects of cancer treatment, such as targeted drug delivery, improved therapeutic effectiveness, and advanced diagnostic capabilities. Specifically, in physiology, electroosmosis-based techniques can significantly enhance the precision and efficiency of drug delivery systems. By leveraging the principles of electroosmosis, targeted delivery of chemotherapeutic agents can be improved, ensuring higher concentrations of drugs reach the tumor site while minimizing systemic exposure and associated side effects.

First, we study the linear stability of the motionless state of a binary mixture in an inclined porous layer under the vertical temperature gradient. It is found that at any layer inclination angle, the most dangerous disturbances are longitudinal rolls with finite wave numbers in perpendicular direction.

The threshold change can reach 26%. Nonlinear calculations are performed for fixed permeabilities of the external layers, lower than the threshold value according to the linear theory. Calculations have shown that after a long period of time from the beginning of the process (about 500 years or more for lower permeabilities), a flow arises.
