| description | Vibrational double diffusion has emerged as a captivating topic in modern research due to its crucial role in improving mixing, disrupting thermal boundary layers, and stabilizing convection structures, particularly in nanofluids and porous media. Given this importance, this study investigates the roles of vibrational impacts on multi-diffusion convection in regular chambers contain non-Darcy porous elements. The flow is modeled as a two-phase nanofluid system, considering both species concentration and nanoparticle concentration. Due to the significance of gravity in such harmonic flows, the domain is inclined, and two-dimensional thermal radiation is applied in both horizontal and vertical directions. The nanoparticles near the heated boundaries are passively controlled. The dimensionless proposed systems are solved via the finite volume technique, and the pressure distribution is handled using an implicit algorithm. Key results show that at a specific time, the modulation amplitude causes a diminishing in the heat transfer coefficients, while at lower time values, it leads to a raising in the vibrational flow. Additionally, a higher rate of heat and mass transport is observed when the vibration frequency is increased. Furthermore, increasing the frequency of oscillation from 200 to 1000 results in a 41.17 % reduction in the heat transfer rate. In contrast, the considered range of thermal radiation leads to a 44.3 % improvement in the heat transfer rate. This work is unique in its combined consideration of vibrational double diffusion, two-phase nanofluid dynamics, bidirectional thermal radiation, and inclined porous chambers under non-Darcy flow, which has not been comprehensively addressed in previous studies. |
