Looking for equations or graphs related to re-entry heat. Assuming a human-shaped object weighing 350 pounds. Starting with a 0 vertical and horizontal velocity @100km. Looking for the G's you would pull on deceleration given the same problem.

When looking up articles about theses problems there was a lot of mention of compressible and incompressible flow how does that relate to re-entry heating?There are some approximations, but generally, simple equations don't exist, only graphs. For example, there is a graph of the destruction altitude of a solid sphere of metal reentering at orbital velocity.
In your case, you would need the approximation for eccentricity just below 1 and 100 km apogee during a ballistic reentry.
Sorry, bad example for equations, since these assume that the drag force is much stronger than gravity and this the effects of gravity can be ignored. But this is not the case for your scenario. But it could ,aybe be adapted to give you an approximation, by calculating the terminal velocity first of your "human shaped object" (You don't want to treat objects like humans, do you?) and then use this as your initial ballistic reentry velocity [math]v_e[/math].

Actually, its 155 MJ (just check the orders of magnitude)
