“…IBM offers a boundary non-conforming approach to resolving flows through complex geometries. The current IBM implementation is within the framework of an in-house code GenIDLEST [24] (Generalized Incompressible Direct and Large Eddy Simulation of Turbulence) and has been extensively validated and applied in a wide range of fluid flow and heat transfer problems [25][26][27]. The applicability of this framework to complex reconstructed porous media geometries including to problems involving species diffusion has been shown to be a promising avenue for simulations involving realistic porous media [26].…”

“…In addition to these, a special test problem is created that presents a stringent check regarding the correctness of the physics being modeled in the sub-pore system and is described here. Since the IBM framework that is used to model the macro-pores has been validated and applied for a wide variety of cases in the past [25,26], a test problem is used wherein the macro-pores can be alternately modeled to be part of the sub-pore system, allowing comparison of results obtained from simulations with and without macro-pore modeling.…”

“…Conjugate heat transfer simulations, where the energy equation is also solved inside the immersed body, using IBM were also reported in [28][29][30][31]. However, to the best of the authors' knowledge, most of these works are based on the extension of the IBM forcing method to heat transfer.…”

The current work focuses on the development and application of a new finite volume immersed boundary method (IBM) to simulate three-dimensional fluid flows and heat transfer around complex geometries. First, the discretization of the governing equations based on the second-order finite volume method on Cartesian, structured, staggered grid is outlined, followed by the description of modifications which have to be applied to the discretized system once a body is immersed into the grid. To validate the new approach, the heat conduction equation with a source term is solved inside a cavity with an immersed body. The approach is then tested for a natural convection flow in a square cavity with and without circular cylinder for different Rayleigh numbers. The results computed with the present approach compare very well with the benchmark solutions. As a next step in the validation procedure, the method is tested for Direct Numerical Simulation (DNS) of a turbulent flow around a surface-mounted matrix of cubes. The results computed with the present method compare very well with Laser Doppler Anemometry (LDA) measurements of the same case, showing that the method can be used for scale-resolving simulations of turbulence as well.

“…Kang et al [31] proposed an implementation in their immersed boundary framework for a multi-material thermal interaction problem. Nagendra et al [32] developed an IB method applicable to a boundary non-conforming mesh with curvilinear coordinates, in which treatments for various thermal boundary conditions for convective and conjugate heat transfer are presented. Another treatment for conjugate heat transfer has been proposed by part of the present authors [33,34] for establishing the interfacial heat flux so as to satisfy the thermal relation at the interface.…”
