The particle temperature as a function of time within the solidus-liquidus temperature range is given by: (Cp + 3.L(Tl-Tg)**2/DTLS**3).log((Tg-Tp)/(Tg-T0)) + 3L/DTLS**3(2Tl-Tg-0.5(Tp+T0))(T0-Tp) = alpha.t/mass where: alpha - particle heat transfer coefficient DTLS - solidus-liquidus temperature range L - latent heat of solidification mass - particle mass t - time (time=0.0 when Tp=Tl) Tg - continuous-phase temperature Tl - liquidus temperature Tp - particle temperature T0 - particle initial temperature ENDDIS REAL(WIN);WIN=100.0 STEADY=F;GRDPWR(T,5,1.0E-02,1.0) GRDPWR(X,5,1.0,1.0) SOLVE(P1,U1);STORE(TMP1) TMP1=GRND1;TMP1A=500.0 FIINIT(U1)=WIN;FIINIT(P1)=RHO1*WIN;FIINIT(TMP1)=500.0 PATCH(GXIN,WEST,1,1,1,1,1,1,1,LSTEP) COVAL(GXIN,P1,FIXFLU,RHO1*WIN);COVAL(GXIN,U1,ONLYMS,WIN) PATCH(GXOUT,EAST,NX,NX,1,1,1,1,1,LSTEP) COVAL(GXOUT,P1,FIXP,0.0) LSWEEP=1 TRACE=F #GENTRA *------------------------------------------------------- * GENTRA GROUP 1: Particle physics *------------------------------------------------------- * Particle type - 50 - MELTING/SOLIDIFYING_PARTICLES GPTYPE=50 * Gravity components in GENTRA Cartesian system/buoyancy GGRAX=0;GGRAY=0;GGRAZ=0;GBUOYA=F * Stochastic model of turbulence GSTOCH=F * Data for melting/solidifying particles GDRAG=GRND1;GKONC=3.3400E-02;GNUSS=1.9060E+01 GLHEAS=2.5000E+05;GSOLIN=3;GSOLST=1450 GLIQST=1600;GCPLIQ=1000;GHLIQD=GRND1 GCPSOL=1000 *------------------------------------------------------- * GENTRA GROUP 2: Boundary conditions for particles *------------------------------------------------------- * Inlet-data file-name GINFIL=Q1 * Use this space for inlet-data table if GINFIL=Q1*_XP_UP_DI_LDEN_MDOT_TEM_SDEN_(NUM)_(STR)_(END) 0.1 100 5e-5 8000 1e-6 1800 8000 * Wall treatment, and rest coefficient if appropriate GWALLC=3;GWREST=1 * Porosity threshold GPOROS=0 *------------------------------------------------------- * GENTRA GROUP 3: Numerical controls *------------------------------------------------------- * 1st GENTRA sweep; frequency of calls GSWEP1=1;GSWEPF=1 * Maximum Lagrangian time-step; time step size multplier GDTMAX=1;GRTFRC=1 * Min # of t-steps per cell; max # of t-steps; timeout GLAGTS=50;GSTEMX=0;GTIMMX=0 *------------------------------------------------------- * GENTRA GROUP 4: Output controls *------------------------------------------------------- * Restart-file, history-file and frequency for output GRSFIL=NONE;GHFILE=GHIS;GOUTFR=1 * The identifier of the individual history and trajectory files GH1STC=H;GT1STC=NONE * The first, last particles and the interval for writing history and trajectory files NGWSTR=1;NGWEND=10;NGWINT=1 * Particle number for residence-time calculation GRESTI=0 *------------------------------------------------------- * GENTRA GROUP 5: Provisions for the GENTRA-Earth run *------------------------------------------------------- * Storage for interphase sources of momentum STORE(MOMX) * Interphase sources of heat and momentum PATCH(GENPAT,CELL,1,NX,1,NY,1,NZ,1,LSTEP) COVAL(GENPAT,U1,FIXFLU,GRND) * Relaxation of interphase sources GLNRLX=1 RELAX(MOMX,LINRLX,GLNRLX) SPEDAT(SET,GXMONI,TRANSIENT,L,F) * Activation of GENTRA GROUND-station L(GENSET * ---------------------------------------------------------- * GENTRA GROUP 7: GENTRA test * ---------------------------------------------------------- * GENTRA auto test RG(51)--RG(58) are reserved RG(51)= 2.90E-02;RG(52)= 7.38E+02;RG(53)= 5.90E-04 RG(54)= 8.40E+00;RG(55)= 7.50E+00;RG(56)= 7.50E+00 RG(57)= 1.74E+01;RG(58)= 7.00E-01 EX(P1)=1.000E+02;EX(U1)=1.000E+02;EX(TMP1)=5.0E+02
