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 (Fc, c, blue line) and enthalpy (Fe, c, orange line) fluxes at the top of the TRAC region, and the radiative losses (ℛTRAC, red line) and heating (QTRAC, 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 (Tc), TRAC region thickness (ℓ), radiative losses integrated across the TRAC region (ℛTRAC) and total over half of the loop (ℛTOTAL), 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.
