In.this work, n.w composite membran.s were successfully prepared via phase in.ersion.techn.que usin. polyvin.l chloride(PVC) an. polyvin.lpyrrolidon.(PVP) as polymers an. tetrahydrofuran.THF) an. n.methyl-2-pyrrolidon.(n.P) as solven.s. The prepared membran.s have been.characterized by scan.in. electron.microscope(SEM), an. fourier tran.forms in.rared spectroscopy(FTIR). The scan.in. electron.microscope results prove that the prepared membran.s are smooth an. their pores are distributed throughout the whole surface an. bulk body of the membran. without an. visible cracks. The stress–strain.mechan.cal test showed an.excellen. mechan.cal behavior en.an.ed by the presen.e of PVP in.the prepared membran.s. The membran.s performan.e results showed that the salt rejection.reached 98% with a high flux. This, in.turn. makes the prepared membran.s can.be applied for sea an. brackish water treatmen. through membran. distillation.techn.logy.

The dyn.mic displacemen. an. dyn.mic thermal momen. of the beam are an.lyzed takin. in.o con.ideration.that the temperature gradien. is in.epen.en. as well as depen.en. on.the beam displacemen..

The type of boun.ary con.ition. has its in.luen.e on.the magn.tude of dyn.mic displacemen. an. dyn.mic thermal momen.. A sustain.d thermally in.uced motion.is observed with progress of time when.the temperature gradien. bein. evaluated is depen.en. on.the forced con.ection.gen.rated due to beam motion. A fin.te elemen. method (FEM) is used to solve the structural equation.of motion.as well as the heat tran.fer equation.
