We obtai. an exact analyti.al soluti.n of the Klei. Gordon equati.n for the equal vector and scalar Rosen Morse and Eckart potenti.ls as well as the pari.y-ti.e （PT） symmetri. versi.n of the these potenti.ls by usi.g the asymptoti. i.erati.n method. Although these PT symmetri. potenti.ls are non-Hermi.i.n, the correspondi.g ei.envalues are real as a result of the PT symmetry.

The effects of a harmoni.ally exci.i.g monopole source on an i.fi.i.ely long cyli.dri.al cavi.y embedded enti.ely wi.hi. a flui.-saturated poroelasti. formati.n of i.fi.i.e extent are exami.ed theoreti.ally. i. i. assumed that the source i. located outsi.e the cavi.y at a speci.i.d di.tance from the borehole axi.. The magni.udes of the hoop and radi.l stresses besi.e the pore pressures exerted on the i.terface and i.si.e the porous medi.m surroundi.g the borehole are calculated and di.cussed. Bi.t's poroelasti. modeli.g along wi.h three types of boundary condi.i.ns for the cyli.dri.al i.terface i.cludi.g the i.eal flui., empty borehole, and ri.i. i.clusi.n wi.h a hard boundary i. employed for the analysi.. Uti.i.i.g a proper translati.nal addi.i.n theorem for expressi.g the i.ci.ent spheri.al wave i. terms of cyli.dri.al wave expansi.ns, the proposed boundary condi.i.ns at the i.terface are sati.fi.d. Stresses are formulated by means of wave potenti.l functi.ns i. a three-di.ensi.nal(3D) manner. The effects of the frequency and the radi.l di.tance between the source and borehole on the i.duced stresses are exami.ed for the fi.st cyli.dri.al modes over frequency spectra. Two permeabi.i.y condi.i.ns for the i.terface and three types of soi.s for the porous formati.n are consi.ered throughout the analysi.. To gi.e an overall outli.e of the study, a numeri.al example i. presented. The results clearly i.di.ate that the di.tance i. a key parameter and has consi.erable effects on the i.duced stress values. i. addi.i.n, the i.terface permeabi.i.y condi.i.n and soi. characteri.ti.s play an i.portant role i. determi.i.g the dynami. response of the borehole. Fi.ally,the obtai.ed results are compared wi.h the relevant analyses exi.ti.g i. the li.erature for some li.i. cases, and good agreement i. achi.ved.

The fi.ter housi.g model was proposed for a heavy-duty i.dustri.l gas turbi.e plant operati.g at an average ambi.nt temperature of 20℃.The pressure drops across the classes of fi.ters were 652.8 Pa, 2692.2 Pa, 887.8 Pa, 776.2 Pa and 2304.2 Pa for i.GB, GB-GA, GA-FA, FA-HA, and HA-o, respecti.ely. The results obtai.ed i.di.ated an acceptable total pressure drop of 7.2% for the enti.e fi.ter housi.g before fi.ter clean-up. Although the CFD si.ulati.n result shows that small outlet flow veloci.y and transoni. flows exi.t at the outlet of the fi.ter housi.g, the desi.ned fi.ter housi.g was proved compati.le wi.h the studi.d GT, for i.let flow condi.i.ns between 600≤ Wai.≤610 kg/s and 60≤Vai.≤70 m/s for the ai. flow rate and veloci.y, respecti.ely. Furthermore, the desi.ned fi.ter housi.g could be adopted for the studi.d GT and locati.ns of Usan and Mai.uguri.i. Ni.eri., and other locati.ns wi.h si.i.ar envi.onmental condi.i.ns.
