Table 2

A summary of the terms from Eq. (2)that control the plasma response to the apex and fp1 heating events, considered in Sect. 4, from the HYDRAD results.

Case Fc,0 balances utr balances Fc,0 Fc,0 drives upward Fe,0 First density peak
(heating location) (Fe,0 reduced due to terms associated with N) (peak density)

1 (apex) 0–12 s 12–15 s 15–100 s (15–40 s) 100 s (500 s)
1 (fp1) 0–5 s 5–8 s 8–100 s (8–35 s) 100 s (500 s)

2 (apex) 0–65 s 65–80 s 80–500 s (80–150 s) 800 s
2 (fp1) 0–20 s 20–40 s 40–500 s (40–100 s) 800 s

3 (apex) 0–40 s 40–45 s 45–270 s (45–50 s) 300 s (1000 s)
3 (fp1) 0–13 s 13–25 s 25–230 s (25–30 s) 300 s (1000 s)

4 (apex) 0–190 s 190–230 s 230–1000 s (230–300 s) 700 s (1500 s)
4 (fp1) 0–50 s 50–90 s 90–900 s (90–120 s) 500 s (1500 s)

Notes. The columns show the time interval during which conductive heating (Fc,0) balances the radiative losses (utr), the rate of change of total energy in the UTR () balances the conductive heating, conductive losses drive an upward enthalpy flux (with the upflow, Fe,0, reduced due to terms associated with N) and the time of the first density peak (and subsequent peak density).
