Effects of variable heat flux at supercritical pressure in vertical pipe flow

•High-fidelity numerical simulation is employed to examine the role of non-uniform heat ux at supercritical pressure.•Axially varying heat ux results in the peak and valley in the wall temperature, indicating a possible heat transfer deterioration control approach.•Thermal stratification was observe...
