Th am of h ar s o valda a modl comud wh a flud rssur dndng on flud sd and dvc' body dmnsons for omal lcrc rsons. Ky words: urbulnc flow, Brnoull ngraon nson, rssur analyz 1. INTRODUCTION W obsrvd h dndnc of h rssur ald on h dvc body facs wh h squar sd of h flud. Th ald rssur s n charg of h zo-rsons hrough s nrnal srss nsor, whch furhr ouus an lcrcal sgnal [1],[],[]. Hr h dvc s a dcor of a flud sd,flud ha can hav dffrn vscoss. Th mahmacal modl has hr subsysms, such as h urbuln flud moon, h sold mchanc and h zolcrc comonns, machd by h boundary and nal condons. Th hyscal dvc consss n a zolcrc rob and a foam mound bwn wo mal lcrods [4],[6], wch allows h zolcrc onal o b masurd, as w rsnd n our rvous ar[7]. So w sarch for a mos smlfd numrcal modl o nvsga h qualav bhavor of h zolcrc dvc and h urbuln flow. Ths modl has o b valdad by comarson wh h rsuls from our rvous rsarch, o furhr nvsga anohr roosd dvc.. A BERNOULLI INTEGRAL EXTENSION W assum ha h rssur ald on h mllmr dvc dnds wh h squar sd of h flud. L s frs rov hs assumon: W sarch for h rssur quaon of h modl bul on our rvous sudy [7]. As a gnral rul, h roduc u can b wrn as h addon bwn a gradn and a vcor roduc among a roor and h vcor flud fld: 1 r u = ( u u ) [( rou) u], In h lar assumon h vlocy fld s an rroaonal fld ( rou r = ), so w oband h rlaonsh for h rssur. 1 = u u ν ( ) ν δ ν ( ) ( ν ρ) δ cons Hnc h rsson abov suggss ha h rssur dnds on h sd s squar.

MATHEMATICAL SUPPORT Th quaons w ar loong for ar h classc consrvaon quaon [5]: ρ u ( u ) = [ δ ( ) ν ν ( ν ν ) δ ρδ, (1) whch by comonns bcoms: ( ) ρu = δ ν ν, () ( ν ν ) δ ρδ and quvaln ( ) ρu = δ ν ν ( ν ν ) ( ν ν ) δ ( ν ν ) δ ρ δ, = 1, and h quaon gvng h roduc rm P, () u u u P = ν, (4) ρ whr h noaons ar: u -vlocy flud fld s comonns (SI un: - m s ), - ρ -dnsy of h flud (SI un: g m ), - - rssur of h flud (SI un: Pa ), - - nc nrgy (SI un: m s ), - ε - s ra of dssaon (SI un: m s ), - ν - dynamc vscosy (SI un: g ( m s) ), ν - - urbuln vscosy (SI un: Pa s ), - ν ff - ffcv vscosy (SI un: Pa s ), s[7]. 4.
