A simple kinetic theory to exhibit a discontinuous shear thickening (DST) is proposed. The model includes a collision integral, a drag from environment and an environmental temperature Tex as well as a shear term. The viscosity of this model is proportional to for large shear rate , while it is independent of for low sheae rate. The emergence of the DST is enhanced for lower density and lower nonzero Tex.
