AbstractWe conduct simulations using the three-dimensional (3D) solar-interplanetary conservation element/solution element (SIP-CESE) magnetohydrodynamic (MHD) model and magnetogram data from a Carrington rotation (CR) 1897 to compare the three commonly used heating methods, i.e. the Wentzel-Kramers-Brillouin (WKB) Alfven wave heating method, the turbulence heating method and the volumetric heating method. Our results show that all three heating models can basically reproduce the bimodal structure of the solar wind observed near the solar minimum. The results also demonstrate that the major acceleration interval terminates about 4R(S) for the turbulence heating method and 10R(S) for both the WKB Alfven wave heating method and the volumetric heating method. The turbulence heating and the volumetric heating methods can capture the observed changing trends by the WIND satellite, while the WKB Alfven wave heating method does not.; We conduct simulations using the three-dimensional (3D) solar-interplanetary conservation element/solution element (SIP-CESE) magnetohydrodynamic (MHD) model and magnetogram data from a Carrington rotation (CR) 1897 to compare the three commonly used heating methods, i.e. the Wentzel-Kramers-Brillouin (WKB) Alfven wave heating method, the turbulence heating method and the volumetric heating method.
