|Current sheets are common structures in the solar wind and are a significant source of solar
wind MHD turbulence intermittency. They can arise from non-linear interactions of
MHD turbulence or be relic structures in the solar wind that having a solar origin.
Observations show that magnetic field directions often change
abruptly upon crossing these structures. The presence of these structures can affect the
transport of solar energetic particles. To understand the effects of these current sheet
a realistic solar wind model that includes them is necessary.
In this work, we construct a realistic solar wind model that
explicitly includes current sheets. In our model, the solar wind is composed of
individual cells with varying local uniform mean magnetic fields.
The size of the individual cells are adjusted to agree with in-situ observations at 1 AU.
The turbulence in each cell is modeled by either a slab and/or 2D turbulence.
