Open AccessUse of dipeptidyl peptidase-4 inhibitors was associated with a lower risk of Parkinson’s disease in diabetic patients
Diabetes mellitus is a risk factor for Parkinson's disease (PD). While animal studies have supported the benefits of incretin-based therapies, including dipeptidyl peptidase-4 (DPP4) inhibitors, in PD, clinica...

Applications of Boundary-Layer Methods: Flows Without Separation
In this chapter we discuss the applications of the boundary-layer method to laminar and turbulent flows without flow separation; flows with separation are addressed in the following chapter. In Section 6.2 we ...

Companion Computer Programs
In this chapter we describe two computer programs. The computer program of Section 10.2 is for steady airfoil flows based on the Hess-Smith panel method (HSPM). The computer program in Section 10.3 is based on...

Chapter
Panel Methods
Panel methods are ideal for calculating the flowfield over an airfoil executing unsteady time-dependent motion in an inviscid incompressible medium. The unsteady motion on the airfoil causes continuous vortex ...

Chapter
Applications of Navier-Stokes Methods
Navier-Stokes (NS) methods are more general than those based on interactive-boundary-layer (IBL) theory and can be used to solve some airfoil flows that IBL methods cannot. For example, as discussed in Chapter...

Chapter
The Differential Equations of Fluid Flow
The differential equations of fluid flow are based on the principles of conservation of mass, momentum and energy and are known as the Navier-Stokes equations. For incompressible flows and for flows in which t...

Applications of Panel Method
In this chapter the panel method described in Chapter 3 is applied to the basic unsteady aerodynamic problems described in the first chapter, namely the problems of lift and thrust generation, airfoil flutter ...

Chapter
Navier-Stokes Methods
Numerical methods for the solution of boundary layer equations were discussed in Chapter 5 and here the discussion is extended to the Navier -Stokes equations for incompressible and compressible flows. Forms o...

Chapter
Physics of Unsteady Flows
Standard textbooks on aircraft aerodynamics either omit any discussion of unsteady aerodynamic effects or, at most, devote a. single chapter to it. A more detailed discussion of unsteady aerodynamics is usuall...

Boundary-Layer Methods
This chapter is concerned with the solution of the boundary-layer equations of subsection 2.4.3 for boundary conditions that include a priori specification of the external velocity distribution either from exp...

Chapter
Applications of Boundary-Layer Methods: Flows with Separation
The calculation method of the previous chapter is limited to flows without separation. As discussed in Section 5.2. the boundary-layer equations for steady flows become singular at the vanishing of wall shear,...
