Temperature-constrained pulse-power limits in parallel microchannel cooling with unresolved flow maldistribution

Numerical code and data supporting the manuscript"Temperature-constrained pulse-power limits in parallel microchannelcooling with unresolved flow maldistribution". This version retains the original two-channel archive (code_and_data.zip)unchanged and adds array_extension_code_and_data.zip, containing thefour- and eight-channel extension. The extension covers 172 flow allocations, four independent heat-sourceconfigurations and 18 pulse schedules, with selected spatial and temporalrefinement checks. It includes source code, retained numerical outputs,verification records and reproduction instructions. Across array sizes, pressure and mean branch flow are fixed, total coolantflow scales with channel count, and one pitch is heated at a time.The results are conditional numerical estimates, not experimentallyvalidated device ratings. No third-party full-text articles are included.
