    Complex dynamics of multi strain TB model under nonlocal and nonsingular fractal fractional operator
    (Elsevier, 2021) Adnan; Ahmad, Shabir; Ullah, Aman; Riaz, Muhammad Bilal; Ali, Amir; Akgul, Ali; Partohaghighi, Mohammad
    Researchers have recently begun to use fractal fractional operators in the Atangana-Baleanu sense to analyze complicated dynamics of various models in applied sciences, as the Atangana-Baleanu operator generalizes the integer and fractional order operators. To analyze the complex dynamics of the multi-strain TB model, we use the AB-fractal fractional operator. We use the Banach fixed point theorem to ensure that at most one solution exists to the model. Further, the Ulam-Hyers type stability of the model is investigated with the help of functional analysis. The Adams-Bashforth approach is used to get numerical results for the proposed model. The analysis of the chaotic behavior of the proposed TB model was missing in the literature. Therefore, for different values of fractional and fractal order, we study the nonlinear dynamics and chaotic behavior of the obtained results of the proposed model.

    (Elsevier, 2023) Adnan; AlBaidani, Mashael M.; Mishra, Nidhish Kumar; Alam, Mohammad Mahtab; Eldin, Sayed M.; AL-Zahrani, Asla A.; Akgul, Ali
    Applications: The fins performance under natural convection is essential to make it more functional for large scale applications more specifically in thermal engineering. For this, it is important to introduce new techniques to enhance the fins performance instead of traditional way. Thus, this study introduces a new way to make the fin more efficient using ternary nanomaterial under nanoparticles shape factor. The annular fin significantly contributes in electronics to exhaust the hot air, injector pumps and applied thermal engineering.Purpose: and Methodology: This work focuses on the fin energy model using shape factors. Therefore, the ternary nanofluid, natural convection, thermal radiation and magnetic field used to develop the model. Then, the RKF-45 implemented to investigate physical results.Core findings: Keen analysis of the physical results reveal that the coefficient of thermal conductivity ranging from 0.0% < alpha 1 < 3.0% and natural convection have major role in the fins energy performance. Induction of magnetic field and thermal radiation Rd are reliable for the fin cooling and, heating source Q1 = 0.2,0.4,0.6,0.8 promote the fin energy capability in the existence of (Al2O3-CuO-Cu) ternary nanomaterial with concentration factor up to 2%. On the comparative basis, ternary nanomaterial makes the fin more efficient than hybrid nanomaterial.

    Thermal management in annular fin using ternary nanomaterials influenced by magneto-radiative phenomenon and natural convection
    (Nature Portfolio, 2023) Alharbi, Khalid Abdulkhaliq M.; Adnan; Bani-Fwaz, Mutasem Z.; Eldin, Sayed; Akgul, Ali
    Annular fin is a particular mechanical setup for heat transfer that varies radially and frequently utilize in applied thermal engineering. Addition of annular fin to working apparatus enhance the surface area in contact with surrounding fluid. Other potential areas of fin installation are radiators, power plant heat exchangers and also it plays significant role in sustainable energy technologies. The major objective of this research is to introduce an efficient annular fin energy model influenced by thermal radiation, magnetic forces, coefficient of thermal conductivity, heating source with addition of modified Tiwari-Das model. Then, numerical treatment performed to acquire the desired efficiency. From the results, it is scrutinized that the fin efficiency significantly improved by strengthening the physical strength of a(1), a(2) and ?(1) and the use of ternary nanofluid make it more efficient. Addition of heating source Q(1) make the fin more efficient and radiative number is better to cool it. The role of ternary nanofluid observed dominant throughout the analysis and the results validated with existing data.
