FROUDE NUMBER VARIANCE WITH RESPECT TO THE HYDRODYNAMIC RESPONSE OF A NON-STATIC VEHICLE AT A LOW-LYING FLOODED ROADWAY

In terms of stability, the response static cars in floodwaters has been widely investigated. However, hydrodynamics a non-static vehicle exposed to such events are less explored. Herein study ponders assessment hydrodynamic forces experienced by attempting cross low-lying flooded street. With that regards, Perodua Viva was modeled (1:10) and tested Hydraulics Laboratory under partial submergence sub-critical flows, fulfilling similarity laws. Since Froude number could best analyze flow conditions, behavior have focus this investigation. From outcomes, an inverse relation with respect buoyancy force, along positive trends relating drag, frictional, rolling resistance, were noticed. ABSTRAK: Dari segi kestabilan, tindak balas kereta statik dalam air banjir telah banyak dikaji. Walau bagaimanapun, hidrodinamik kenderaan tidak yang terdedah kepada kejadian seperti itu kurang diterokai. Kajian ini menilai daya cuba melintas jalan raya banjir. Sehubungan itu, sebuah dimodelkan dan diuji Makmal Hidraulik di bawah perendaman separa didedahkan aliran sub-kritikal, ketika kejadian. Manakala nombor adalah terbaik menganalisa keadaan air. Oleh menjadi fokus penyelidikan ini. Dapatan kajian menunjukkan kaitan terbalik pada apungan, sedangkan tren positif berkaitan dengan tarik, geseran rintangan guling diperhatikan.
