Which one Blows Harder?

Endurance Innovation is now on Patreon! Have a peek at our page and show us some love.3:30 Cycling Tips review of fansFan specs: volumetric flow rate, airflow velocity, powerMeasured skin temp, core temp, heat fluxUsed an array of Core body temp sensors Compared no fan, small desktop fan, low velocity air mover, wahoo headwind, scroll fanHeat transfer equation: Q=k*A*ΔT, where Q is the heat transfer, k is  the heat transfer coefficient, A is the surface area, and ΔT is the difference between skin temperature and the air around the skinMaximize all three variable to maximize heat transferPerception of thermal comfort vs core temperature39:30 how much does a flappy run top cost in terms of run power?Tight clothing improves wicking and coolingBased on a CdA of 1.0, at 4:00/km, aero drag is 40WFlappy kit may increase CdA by 20% or 8WMichael’s 4:00/km Stryd power is 340W, plus 40W for air resistanceSo floppy kit hit of 8W is an increase of ~2%@ a 5:00/km pace, the aero drag is too small to worry about.Check out our episodes on heat transfer: 112, 115, 32, and the Core Body Temp Sensor page for their webinars and blog posts.
