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 fans Fan specs: volumetric flow rate, airflow velocity, power Measured skin temp, core temp, heat flux Used an array of Core body temp sensors Compared no fan, small desktop fan, low velocity air mover, wahoo headwind, scroll fan Heat 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 skin Maximize all three variable to maximize heat transfer Perception of thermal comfort vs core temperature 39:30 how much does a flappy run top cost in terms of run power? Tight clothing improves wicking and cooling Based on a CdA of 1.0, at 4:00/km, aero drag is 40W Flappy kit may increase CdA by 20% or 8W Michael’s 4:00/km Stryd power is 340W, plus 40W for air resistance So 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.
