Semi-numerical calculations to the maximal fluid distribution behaviour of the MHD peristaltic pseudoplastic-nanofluid flow with dependent conductivity in a hybrid channel: applications to sustainable building technologies

Heat transfer through solar energy absorption has a vital role in many industries and innovates many passive cooling approaches in sustainable architecture, where nanofluid circulation within building envelopes. Consequently, the mutual effects of activation energy and dependent electrical conductivity impact on MHD pseudoplastic-nanofluid in a mixed channel are proposed. Conductivities studied in non-constant cases under the law of Wiedemann-Franz. Adaptive-multi-step differential transform method is used to get the behaviour of tabbed bolus and maximum velocity as well as the velocity, temperature and concentration distribution. Solutions are verified via numerical comparison between prior results and published results by Hasona et al. [2020. “Combined Effects of Variable Thermal Conductivity and Electrical Conductivity on Peristaltic Flow of Pseudoplastic Nanofluid in an Inclined Non-Uniform Asymmetric Channel: Applications to Solar Collectors.” Journal of Thermal Science and Engineering Applications 12 (2): 021018]. Results show that high values of dependent temperature and concentration electrical conductivity can potentially provide more energy. This results in sustainable cooling and optimal energy control. In addition, maximum velocity controls can be better using thermophoresis and Brownian motion parameters, which can improve the heat transmission in solar cells. This study confirms the possibility of linking fluids and architecture in sustainable building modernisation processes.
