GEOMETRIC MODIFICATIONS TO MINIMIZE LIFT ACTING ON A SIMPLIFIED FRONT WINDSHIELD WIPER BLADE

Bu sayısal çalışmada basitleştirilmiş bir araç ön cam geometrisinde sileceklere etkiyen aerodinamik direnç ve kaldırma kuvvetleri incelenmiştir. Sileceklere 240 km/h gibi yüksek hızlarda etkiyen kaldırma kuvvetini azaltmak için farklı rüzgârlık profilleri, silecek yüksekliği ve sileceğin rüzgârlık ile metal parçası arasında olan bağlantı şekilleri incelenmiştir. İncelenen geometrik özellikler daha sonra birleştirilerek yüksek hızlarda kaldırma kuvvetlerini azaltma bağlamında faydalı olabilecek yeni silecek geometrileri önerilmiştir

BASİTLEŞTİRİLMİŞ BİR ÖN CAMDA SİLECEK GEOMETRİSİNE ETKİ EDEN KALDIRMA KUVVETLERİNİN AZALTILMASINA YÖNELİK GEOMETRİK DEĞİŞİKLİKLER

In this numerical study, aerodynamic lift and drag forces acting on windshield wipers operating on a simplified front windshield of a car are investigated. Geometric modifications including spoiler curvature, total wiper height and connection between metal part and spoiler of the wiper are tested with the aim to reduce lift forces acting on the front windshield wiper blades at high speeds such as 240 km/h. The inference of the investigated geometric modifications is then proposed as a useful wiper prototype which can be applied to minimize lift forces at relatively high speeds
