 Optimum Stirling Engine Geometry, James R. Senft, 2002. International Journal of Energy Research, Int. J. Energy Res. 202; 26; 10871101
 Very nice work, Shows tricky influence of the effectiveness of the
mechanical drive mechanism including the energy exchange between power piston
and flywheel. This has an important influence on the optimum choice
for the ratio of piston to displacer swept volume ratio and angle by which the
displacer piston motion leads the power piston.(I have hardcopy and some
handwritten notes)
 A review of solarpowered Stirling engines and low temperature
differential Stirling engines, Kongtragool Wongwise, 2003.Renewable &
Sustainable Energy Reviews, 7 (2003) 131154
 Offical abstract:
This article provides a literature review on solarpowered Stirling
engines and low temperature differential Stirling engines technology.
A number of research works on the development of Stirling engines,
solarpowered Stirling engines, and low temperature differential Stirling
engines is discussed. The aim of this review is to find a feasible
solution which may lead to a preliminary conceptual design of a workable
solarpowered low temperature differential Stirling engine.
Results from the study indicate that Stirling engines working with
relatively low temperature air are potentially attractive engines
of the future, especially solarpowered low temperature
differential Stirling engines with vertical, doubleacting,
gammaconfiguration.

 Active Stirling Engine, Gopal, V. Duke, R. Clucas, D., 2009
Singapore: TENCON 2009: IEEE Region 10 Conference, 2326 Nov 2009
 Official abstract : In this paper the WhisperGen micro combined heat and power (microCHP) system, its advantages, control and possible scope for improvement are explored. Concept of active Stirling engine (ASE) is introduced. A test rig designed to test possible improvements of the efficiency and controllability of a kinematic Stirling engine based microCHP system is explained."
My take: a) High temperature machine using waste heat as heat source to home, etc,i b) Modifying displacer motion to achieve larger dwell times (up to 33%) at
the two extreme positions in order to increase ∫ p dV.

 A new isothermal theory for Stirling machine analysis
and a volume optimization using the concept of
‘ancillary’ and ‘tidal’ domains, T Finkelstein, 1998
Proceedings of the Institution of Mechanical Engineers, Part C: Journal
of Mechanical Engineering Science 1998 212: 225
 Abstract:
Theoretical studies of Stirling cycle machines have always utilized a topological system
view that goes back to Schmidt’s isothermal analysis, where the process is analysed by reference to
the expansion space volume variations. Due to this idiosyncrasy in the formulation, it has been
difficult to deduce meaningful design criteria from the results. In this paper an alternative visualization
is presented, using the newly introduced concepts of a ‘tidal phase angle’ and overlapping ‘tidal’ and
‘ancillary’ domains. With vectorial parameters and a centralized reference basis, a nondimensional
parameter Rtcr, the ‘tidal compression ratio’, equal to the ratio of the average masses in the tidal and
ancillary domains, is derived. This number uniquely characterizes the operation of equivalent
machines and is therefore akin to the compression ratio in internal combustion engines. On the basis
of this, a second new parametric grouping emerged to enhance the usefulness of the resultant integrated
equations for use with dimensional analysis. It was defined as the ‘specific performance’ Nsp
and is proportional to the output per unit mass, the gas constant and the operating temperature
range. It is applicable to engines, heat pumps and refrigerators.
Prior attempts at optimizing the proportions of a Stirling engine have not yielded usable results
and consequently nearly all Stirling cycle machines built up to the present time have expansion and
compression spaces of equal size. The new analysis shows that this is not the most appropriate
configuration and it readily yields an optimization of the component volumes. One single analytical
conditional equation for the optimum relative sizes of the constituent spaces was obtained from the
new formulation for performance that quantifies the condition for an optimized proportioning of
any Stirling cycle machine. It has three distinct usable solutions, one of which is an analytical confirmation
of a postulate that has previously been published by the author without proof, equating
VE/VC and also Vh/Vk to the temperature ratio TE/TC.
A numerical verification of this rule based on the proportions of the United Stirling V160 engine
compares it with 12 equivalent reproportioned derivative engines, all with equal charge masses and
operating at precisely the same conditions. This shows a substantial increase in the ideal performance
through the use of the derived criteria. The main conclusion is that this theory may lead to a
reexamination of the overall layout of Stirling cycle machines and the emergence of a new class of
machines with superior performance.
On page 9/13 (Table 1) we find some data on the United Stirling V160 engine
which is an alphatype engine :
VE = 159.8 Vh=71.2 Vr=83.8 Vk=96.9 VC=159.8 Te=993 Tc=288 cm³ Pm=1.25*10^7
Pa = 125*10^5Pa = 125 atm
He introduces the variation of the volume of the expansion space as
VE/2*cos(Φ+A) and that of the compression space as
VC/2*cos(ΦA) where 2*A = traditional phase lag angle.i (see his Eq.(1))
Comparing his Eq.(6) and (8) shows clearly that Finkelstein is somewhat
loose with his symbols. In (6) he uses V_{e} and in (8) V_{E}
to describe the volume variation of the expansion space. Same holds true
for the expansion space.
There is no mention of the clearance volumes (= minimum volume of the
compression and expansion space and connecting space for gammatype)

 THE EXPERIMENTAL V4X STIRLING ENGINE – A PIONEERING DEVELOPMENT, Professor Gunnar Lundholm, 2004
 This is a nice account of the development towards the V4X36 automobile
engine. It was roadtested for about 10000 km in a 1974 Ford Taunus. This engine was used in a 50’ies Porsche Bergspider racing car
with a top speed of 200 km/hour. A prior engine, the V4X31 installed in a
Ford Pinto, was probably the first directdriven Stirling engine car in
the world.

Results on oscillating flow start on page 137 (acroread) with the investigation
of transition to laminar. They compare their own experimental data to the
numerical predictions. Conclusions about the oscillating flow are on pdfpage

"For Remax numbers above 10^{5}, the steady state correlations
for the fully developed friction coefficient and Nu number apply well.
For lower Remax numbers, the
departures become larger with decreasing Remax and increasing Va.
