Body-fitted topology optimization of 2D and 3D fluid-to-fluid heat exchangers

Abstract: We present a topology optimization approach for the design of fluid-to-fluid heat exchangers which rests on an explicit meshed discretization of the phases at stake, at every iteration of the optimization process. The considered physical situations involve a weak coupling between the Navier-Stokes equations for the velocity and the pressure in the fluid, and the convection-diffusion equation for the temperature field. The proposed framework combines several recent techniques from the field of shape and topolog… Show more

“…However, if this accurate boundary description cannot be converted to the model for the post‐processing, simulation, and manufacturing, the ability of this accurate description makes less sense than it should. Therefore, the surface capturing techniques are highly recommended such as X‐FEM 31 and body‐fitted adaptive mesh 52 Flow modeling and computational cost.…”

“…How should the fluid flow so that the container cools as quickly as possible? This question arises, for instance, in the design of optimal heat exchangers, whose complicated shapes and flows facilitate heat transfer at rates far beyond diffusion [1][2][3][4][5][6][7][8][9][10]. More generally, the problem is related to the ongoing search for sharp bounds on turbulent heat transfer in a variety of settings, including internally heated [11][12][13][14][15][16] as well as buoyancy-driven convection [17][18][19][20][21], among others.…”

“…Instead, we propose to use topology optimization [52] to computationally guide flow field design. This method has seen significant advancements in recent years, and researchers have used topology optimization to aid in the design of heat exchangers [53,54,55,56,57,58], structural supports [59,60], and microfluidic devices [61,62]. Additionally, topology optimization has been applied to the design of two-dimensional flow fields for both flow batteries [63,64] and fuel cells [65].…”
