文摘
- •
The effect of woven spacers on heat transfer and friction in channels was studied.
- •
Experiments were performed by Thermochromic Liquid Crystals and image processing.
- •
Numerical simulations were performed both for steady and unsteady flow.
- •
A good agreement was obtained for the Nusselt number and the friction coefficient.
- •
Results are relevant for the optimum design of Membrane Distillation (MD) modules.
