Abstract As a continuation of previous publications on a physical-mathematical model of heat and mass transfer and a structural model of mat permeability, this paper presents typical prediction results for 15 pressing variables for strand mats. A case study and complete solutions to the governing equations are provided. The results show how the heat and mass transfer is controlled by heat conduction and convection involving gas flow and phase change. The model predictions provide a comprehensive illustration of the temporal and spatial variations of basic pressing variables, including mat temperature, gas pressure, moisture control and resin curing rate. The model offers a powerful tool for simulating the effects of mat structure, pressing schedule and initial mat conditions.

An air conditioning system based on a direct contact heat and mass transfer process between water and air may offer benefits such as increased energy efficiency, temperature and humidity control, and improved indoor air quality. To investigate the feasibility of this type of technology, a numeric model is used to study the heat and mass transfer between a single droplet and moist air to gain fundamental insight into the heat and mass transfer process. Further, preliminary experiments are performed in a low speed temperature and humidity controlled wind tunnel to validate some of the models findings, e.g. the effect of droplet size on heat and mass transfer. A case study is presented to investigate how such a system would operate in a hot, dry climate as well as a hot and humid climate.
