Abstract
An assembly can include an exhaust gas turbine housing including an inner wall and an outer wall that define a first exhaust gas channel and a second exhaust gas channel to a turbine wheel space where the inner wall includes an inner wall end at the turbine wheel space and the outer wall includes an outer wall end at the turbine wheel space; a first flow body disposed adjacent to the inner wall end; a second flow body disposed adjacent to the outer wall end; and at least one set of adjustable variable geometry nozzle vanes that define nozzle throats that direct flow of exhaust gas from at least one of the exhaust gas channels to the turbine wheel space, where at least one of the first flow body and the second flow body includes a concave trailing surface that is defined in part by an arc of a circle.
