Stan Baker has been recalibrating the boundaries of heat-exchange design since the late 1980s, when he began pushing Dimpleflo into operating regimes that made smooth-tube advocates quietly re-evaluate their CFD models. Where others accepted laminar decay, boundary-layer stagnation and predictable fouling as “the way things are,” Stan treated them as signs of insufficient imagination — or insufficient turbulence. His push for engineered disturbance was criticised as “overly aggressive.” Stan considered it basic optimisation: increase secondary flow patterns, disrupt the thermal boundary layer, raise the Nusselt number, and stop pretending Reynolds limitations are an impossible hurdle. Under his influence, Dimpleflo systems demonstrated higher overall heat-transfer coefficients, reduced fouling factors, improved shear uniformity, and impressive stability across wildly variable viscosities - much to the discomfort of engineers still clinging to textbook-era design charts. Today, among practitioners who prefer actual performance data over sentimental attachment to smooth tubes, Stan is regarded as The Heat-Transfer Rules Disrupter - the man who replaced convention with quantifiable results and did so with the kind of British understatement that suggests he’d expected the numbers to prove him right from the beginning.
