Abstract: The present work involves the numerical research a pore scale analysis is conducted to explore the actions of microscopic inertia and thermal dispersion in a porous medium. Thermal dispersion in porous media is an import phenomenon for Enhanced Oil Recovery methods including several other engineering applications in combustion and in steam injection systems. The results of thermal dispersion inside cross-flow tubular heat exchangers on heat transfer and temperature zone are numerically examined. Owing to the existence of barriers, thermal dispersion induced by fluid mixing plays a significant role in increasing heat transfer. Accurate calculations of the departure temperature and overall heat transfer rate must also be taken into consideration. The computational process analysis and simulation was developed using the ANSYS method. In this paper, a low Reynolds number flow is considered therefore, flow is regulated by Darcy's law. The present study demonstrates the shift in the centerline temperature values in specific flow directions with variations in relative thermal conductivity magnitude for thermal conductivity of the wood.
