• A thermal multi-component multi-phase LB model is presented.
• Two-component jet flow with heat transfer in a channel is studied by the LB model.
• Extrusion effect has a big influence on two-component jet flow.
• Higher Re of jetting fluid leads to faster flow and heat transfer at channel center.
• Both extrusion effect and momentum diffusivity have major impact on heat transfer.
The two-component jet flow with heat transfer in a channel is numerically investigated by the pseudo-potential lattice Boltzmann method using discretized force treatment coupled with passive-scalar approach. The influences of interaction strength, Reynolds number and Prandtl number of jetting and surrounding fluids on jet flow with heat transfer in a channel are analyzed. Numerical results show that the extrusion effect, which derives from these influence factors, is prominent for fluid distribution and flow.
