Shock Wave Bejeweled



Shock Wave Engine Design by Helmut E. Weber,

Shock Wave Engine Design by Helmut E. Weber,
Written by an author who has devoted the past twenty-five years of his life to studying and designing shock wave engines, this unique book offers comprehensive coverage of the theory and practice of shock wave engine design. The only book treating the complete preliminary design of shock wave engines, it provides engineers with practical step-by-step guidelines applicable to the design and construction of small, lightweight, low-powered industrial turbines as well as high performance jet aircraft engines. In his discussions of the advantages and disadvantages of shock wave versus other types of combustion engines, Dr. Weber demonstrates how and why shock wave engines can be made to work more efficiently than conventional gas turbines. Among other things, he shows quantitatively why combustion temperatures can be significantly higher in shock wave engines than conventional gas turbines. He evaluates temperatures of moving parts in terms of combustion and engine inlet temperatures, and explores the effect of shock coalescence, expansion fan reflections and intersections on port sizes and locations. And throughout, real and imagined performance problems are posed and proven solutions given for shock wave engines - alone and in conjunction with conventional gas turbines or reciprocating internal combustion engines. Designed to function as a practical guide, Shock Wave Engine Design offers concise step-by-step design techniques in a readily usable format. Engineers will find precise, detailed directions on such essentials as how to size wave rotor blade lengths and heights and the correct rotor diameter for a specified power, and material selection for rotor and stator. And one entirechapter (Chapter 12) is devoted exclusively to a detailed example design for a 500 hp engine.

Shock wave - In a supersonic flow the compression of a nonreacting gas can be most simply modelled as an isentropic or Prandtl-Meyer compression, or as a shock wave. When an object (or disturbance) moves faster than the information about it can be propagated into the surrounding fluid, fluid near the disturbance cannot react or "get out of the way" before the disturbance arrives.

Hydrostatic shock - Hydrostatic shock is a theory of terminal ballistics that wounding effects are created by a shock wave in the tissues of the target. The term is meant to be a combination of hydrostatics with the (misnomer) effect of hydrodynamic shock.

Mach wave - A slight change of pressure added to a compressible flow is transmitted as a pressure wave travelling with the speed of sound. These weak waves combine in supersonic waves to become a shock wave.

Shock hardening - Shock hardening is a process used to strengthen metals and alloys, wherein a shock wave produces atomic-scale defects in the material's crystalline structure. As in cold work, these defects interfere with the normal processes by which metallic materials yield (plasticity), making such materials stronger but more brittle.
