Experimental and numerical investigation of the fluid flow in a side-ported rotary engine
TL;DR: In this paper, an optical side-ported rotary engine testbed was built and PIV was employed to measure the flow field in the rotor housing central plane, and a three-dimensional dynamic mesh and turbulent flow model was integrated and simulated using the Fluent CFD software.

Reciprocating Expander for an Exhaust Heat Recovery Rankine Cycle for a Passenger Car Application
TL;DR: In this paper, a steady-state semi-empirical model of the expander device developed under the Engineering Equation Solver (EES) environment is presented. And the model computes the mass flow rate, the power output delivered and the exhaust enthalpy of the steam.

Preliminary design and controlling strategies of a small-scale wood waste Rankine Cycle (RC) with a reciprocating steam engine (SE)
Marco Badami,Massimiliano Mura +1 more
TL;DR: In this article, a small-scale Rankine Cycle (RC) operating as a combined heat and power (CHP) unit and fed by wood waste is studied and the preliminary design and theoretical analysis of the main RC components are presented.

Operating maps of a rotary engine used as an expander for micro-generation with various working fluids
TL;DR: In this paper, an analysis was carried out in a rotary volumetric expander based on the Wankel concept, which was never studied before for this application, in order to evaluate the relationship between the used working fluid, the inlet temperature and the delivered mechanical power.

Numerical study on ignition amelioration of a hydrogen-enriched Wankel engine under lean-burn condition
TL;DR: In this article, the role of the number of the ignition source, twin-spark plug location, asynchronous ignition, and energy allocation in improving lean combustion was investigated through the three-dimensional computational fluid dynamics model coupling with kinetic mechanisms.

Rotary piston expander engine
G A Brown,D A Bowlus +1 more
TL;DR: In this paper, a rotary expander is used for open-cycle or closed-cycle applications, where an air-alcohol-water mixture is burned external to the expander in an experimental combustor and directed to the engine.
