In various particular embodiments, a steam turbine nozzle includes: a body having: a first sidewall and a second sidewall opposite the first sidewall; a pressure side and a suction side each extending between the first sidewall and the second sidewall; and a leading edge section at a first junction of the pressure side and the suction side, and a trailing edge section at a second junction of the pressure side and the suction side; and a bypass fluid conduit including: a channel having an opening to at least one of the first sidewall or the second sidewall; and an outlet passageway fluidly connected with the channel between the first sidewall and the second sidewall, the outlet passageway including a first opening on at least one of the pressure side of the body, the suction side of the body or the trailing edge section. ## Claims ### Claim 1 A steam turbine nozzle comprising: a body having: a first sidewall and a second sidewall opposite the first sidewall; a pressure side and a suction side each extending between the first sidewall and the second sidewall; and a leading edge section at a first junction of the pressure side and the suction side, and a trailing edge section at a second junction of the pressure side and the suction side; and a bypass fluid conduit including: a channel having an opening to at least one of the first sidewall or the second sidewall; and an outlet passageway fluidly connected with the channel between the first sidewall and the second sidewall, the outlet passageway including a first opening on at least one of the pressure side of the body, the suction side of the body or the trailing edge section. ### Claim 2 (depends on 1) The steam turbine nozzle of claim 1, wherein the bypass fluid conduit is configured to allow a fluid to pass from the opening of the channel through the outlet passageway to the first opening on the at least one of the pressure side of the body, the suction side of the body or the trailing edge section. ### Claim 3 (depends on 1) The steam turbine nozzle of claim 1, wherein the first opening has a substantially oval shape including a profile that extends a greater distance between the leading edge and the trailing edge than between the first sidewall and the second sidewall. ### Claim 4 (depends on 1) The steam turbine nozzle of claim 1, further comprising a second opening in the channel to the other one of the first sidewall or the second sidewall. ### Claim 5 (depends on 1) The steam turbine nozzle of claim 1, wherein the bypass fluid conduit further includes a second outlet passageway with a second opening on at least one of the pressure side of the body, the suction side of the body or the trailing edge section. ### Claim 6 (depends on 1) The steam turbine nozzle of claim 1, wherein the channel has a larger inner diameter than an inner diameter of the outlet passageway. ### Claim 7 A turbomachine diaphragm comprising: an inner diaphragm ring; an outer diaphragm ring radially outward of the inner diaphragm ring; and a set of static nozzles spanning between the inner diaphragm ring and the outer diaphragm ring, wherein at least one static nozzle in the set of static nozzles includes: a body having: a first sidewall and a second sidewall opposite the first sidewall; a pressure side and a suction side each extending between the first sidewall and the second sidewall; and a leading edge section at a first junction of the pressure side and the suction side, and a trailing edge section at a second junction of the pressure side and the suction side; and a bypass fluid conduit including: a channel having an opening to at least one of the first sidewall or the second sidewall; and an outlet passageway fluidly connected with the channel between the first sidewall and the second sidewall, the outlet passageway including a first opening on at least one of the pressure side of the body, the suction side of the body or the trailing edge section. ### Claim 8 (depends on 7) The turbomachine diaphragm of claim 7, wherein the bypass fluid conduit is configured to allow a fluid to pass from the opening of the channel through the outlet passageway to the first opening on the at least one of the pressure side of the body, the suction side of the body or the trailing edge section. ### Claim 9 (depends on 7) The turbomachine diaphragm of claim 7, wherein the first opening has a substantially oval shape including a profile that extends a greater distance between the leading edge and the trailing edge than between the first sidewall and the second sidewall ### Claim 10 (depends on 7) The turbomachine diaphragm of claim 7, wherein the at least one static nozzle further includes a second opening in the channel to the other one of the first sidewall or the second sidewall. ### Claim 11 (depends on 8) The turbomachine diaphragm of claim 8, wherein the bypass fluid conduit further includes a second outlet passageway with a second opening on at least one of the pressure side of the body, the suction side of the body or the trailing edge section. ### Claim 12 (depends on 7) The turbomachine diaphragm of claim 7, wherein the channel has a larger inner diameter than an inner diameter of the outlet passageway. ### Claim 13 A turbomachine comprising: a rotor section; and a stator section substantially housing the rotor section, the stator section including: a packing section; and a set of static nozzles spanning between an inner diaphragm ring and an outer diaphragm ring, wherein at least one static nozzle in the set of static nozzles includes: a body having: a first sidewall and a second sidewall opposite the first sidewall; and a pressure side and a suction side each extending between the first sidewall and the second sidewall; and a bypass fluid conduit including: a channel having an opening to at least one of the first sidewall or the second sidewall proximate the packing section; and an outlet passageway fluidly connected with the channel between the first sidewall and the second sidewall, the outlet passageway including a first opening on the pressure side of the body, wherein the bypass fluid conduit is configured to divert a fluid from the packing section to the first opening on the pressure side of the body during operation of the turbomachine. ### Claim 14 (depends on 15) The turbomachine of claim 15, wherein the at least one static nozzle further includes: a leading edge section proximate a first portion of the body; and a trailing edge section proximate a second portion of the body opposite the first portion of the body. ### Claim 15 (depends on 14) The turbomachine of claim 14, wherein the first opening has a substantially oval, rectangular or trapezoidal shape including a profile that extends a greater distance between the leading edge and the trailing edge than between the first sidewall and the second sidewall ### Claim 16 (depends on 13) The turbomachine of claim 13, wherein the at least one static nozzle further includes a second opening in the channel to the other one of the first sidewall or the second sidewall. ### Claim 17 (depends on 13) The turbomachine of claim 13, wherein the bypass fluid conduit further includes at least one additional outlet passageway each with an additional opening on one of the pressure side of the body, the suction side of the body or the trailing edge section. ### Claim 18 (depends on 13) The turbomachine of claim 13, wherein the channel has a larger inner diameter than an inner diameter of the outlet passageway.
