Results for the 600 s heating pulse simulations (Sect. 4.1). Upper four panels: coronal averaged temperature and density as functions of time, and their respective normalised differences. The lines are colour coded in a way that reflects the conduction method used and different values of RL are separated by different line styles as shown in the right-hand panels. Central two panels: comparison of the energetically dominant quantities that are associated with the TRAC region, namely, the heat (F_c, c, blue line) and enthalpy (F_e, c, orange line) fluxes at the top of the TRAC region, and the radiative losses (ℛ_TRAC, red line) and heating (Q_TRAC, green line) integrated across the TRAC region. Solid (dashed) lines indicate where the enthalpy flux is upflowing (downflowing). Lower four panels: time evolution of the cutoff temperature (T_c), TRAC region thickness (ℓ), radiative losses integrated across the TRAC region (ℛ_TRAC) and total over half of the loop (ℛ_TOTAL), and the ratio between these losses (℔_TRAC/℔_TOTAL). We note that the temperature of the TRAC(RL = 5) and SH(RL = 14) solutions overlay in the top left-hand panel.
