Various kinds of PDMS (polydimethylsiloxane),  deionized water, and glycerin-water (85%-15% vol.) mixture  were used to wet the pyramidal arrays and concentric triangular circles,  which have scales in millimeters. Wetting of the test substrates were done  both in vertical and horizontal orientation, by dipping the substrate in a liquid  bath and pumping the liquid through the center of the substrate, respectively.  The apparent contact angle on each substrate was measured and a correlation  between capillary number, contact angle, and feature size was sought. Existing  models and contact angle evaluation methods, together with additional  new approaches, have been applied and were discussed extensively.  Numerical simulations for wetting on horizontally placed substrates were performed  by using a C++ based, open source CFD software package, Open-FOAM (Open Source Field Operation and Manipulation). Kistler¿s dynamic  wetting equation was implemented into the software. Simulation results compatible  with experiments were achieved.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783639707380\"\u003e\u003ch3\u003eWetting on 3D Pyramidal Features\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783639707380","offer_id":39482484883549,"sku":"9783639707380","price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6cd9db2e-b063-4924-86c7-f9d3e400e673.jpg?v=1768890592","url":"https:\/\/shop.autorenwelt.de\/products\/fundamental-investigation-of-forced-wetting-on-structured-surfaces-von-selin-manukyan","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
