Topology optimization of heat sinks
Three-dimensional Navier-Stokes equation for fluid flow and heat transfer equation, and their adjoint equations are solved in each design iteration.
Thermohydraulic tests show that the topology optimized heat sink has 2-fold increase in conductance over optimized parallel fin heat sink without much accompanying pressure loss (Sun et al IJHMT 2024)

Topology optimization of two-fluid heat exchangers
Two sets of Navier-Stokes fluid flow and heat transfer equations are solved, respectively, for fluid 1 and fluid 2.
Minimal wall thickness constraint is imposed to avoid leakage between fluids. Additive manufacturability constraint is also imposed to ensure powder removal from the resulting complex fluid channels.
With the same header, the TO HX outperformed the straight channel HX, reaching 50 kW, while the straight channel HX achieved 41 kW.
