Grid Independence Test Data for Optimized Micro-Channel Heat Sink Design

Junkai Yao published a dataset on figshare in April 2026 containing results from a grid independence test at Reynolds number 11353. The data supports a study proposing a novel micro-channel design with oblique capsule-shaped ribs to enhance cooling for high-power laser diodes. The dataset is 5.5 KB in size and is provided in XLS format.

Use Cases

• Validate computational fluid dynamics (CFD) simulation results for turbulent flow in micro-channels based on the described Reynolds number and geometric parameters.
• Analyze the trade-off between heat transfer enhancement and pressure drop increase based on the reported Nusselt number and friction factor data.
• Benchmark optimization algorithms for thermal-hydraulic performance using the provided performance evaluation criteria (PEC) improvement metric.
• Study the effect of rib geometry on boundary layer perturbation and vortex generation as described in the associated paper.

Strengths

• Dataset is associated with a specific, documented optimization study, providing context for the numerical results.
• Key performance metrics (e.g., 20.2% increase in Nusselt number, 15.6% improvement in PEC) are explicitly stated in the description.
• The optimized geometric parameters for the capsule-shaped ribs are provided with precise millimeter measurements.

Limitations

• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Column-level documentation is absent; field semantics must be inferred from the description or the XLS file after download.
