Experiment based development of a non-isothermal pore network model with secondary capillary invasion

In this thesis, PN simulations of drying are compared with experimentally obtained data from drying of a representative 2D microfluidic network in SiO2 under varying thermal conditions with the aim to identify governing physical pore scale effects. Gravity and viscous effects are disregarded in this thesis. Instead drying with slight local temperature variation and drying with imposed thermal gradients are studied. Based on this investigation, a powerful non‐isothermal PNM is developed. This model incorporates i) the phenomena associated with the temperature dependency of pore scale invasion, namely thermally affected capillary invasion and vapor flow as well as ii) the secondary effects induced by wetting liquid films of different morphology.
