This book was released on 1971 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stagnation-point convective heat transfer to an axisymmetric blunt body for arbitrary gases in chemical equilibrium was investigated. The gases considered were base bases of nitrogen, oxygen, hydrogen, helium, neon, argon, carbon dioxide, ammonia, and methane and 22 gases mixtures composed of the base gases. In the study, enthalpies ranged from 2.3 to 116.2 MJ/kg, pressures ranged from 0.001 to 100 atmospheres, and the wall temperatures were 300 and 1111 K. A general equation for the stagnation-point convective heat transfer in base gases and gas mixtures was derived and is a function of the mass fraction, the molecular weight, and a transport parameter of the base gases. The relation compares well with present boundary-layer computer results and with other analytical and experimental results. In addition, the analysis verified that the convective heat transfer in gas mixtures can be determined from a summation relation involving the heat-transfer coefficients of the base gases. The basic technique developed for the prediction of stagnation-point convective heating to an axisymmetric blunt body could be applied to other heat-transfer problems.

Book Synopsis Stagnation Point Heat Transfer in High Enthalpy Gas Flows. Part I: Convective Heat Transfer in Partially Ionized Air by : Robert M. Nerem
Download or read book Stagnation Point Heat Transfer in High Enthalpy Gas Flows. Part I: Convective Heat Transfer in Partially Ionized Air written by Robert M. Nerem and published by . This book was released on 1964 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using an arc driven shock tube facility, measurements of convective heat transfer at the stagnation point of a blunt body were carried out at simulated flight velocities ranging from 20,000 to 40,000 feet per second. These measurements were performed using standard calorimeter techniques with air as the test media. The results indicate no significant ionization effects on aerodynamic heating and indicate that the Lee's approximate equation for stagnation point heat transfer can be used for engineering calculations at flight velocities up to 40,000 feet per second.

Book Synopsis Stagnation Point Heat Transfer in a Relaxing Gas by : Robert Elliott Wilson
Download or read book Stagnation Point Heat Transfer in a Relaxing Gas written by Robert Elliott Wilson and published by . This book was released on 1963 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stagnation point heat transfer in a gas undergoing relaxation of its internal energy is examined by solution of the equations of motion using the two temperature approach of Wang Chang and Uhlenbeck. The results are presented in parametric form and show that relaxation effects produce an adiabatic wall temperature above the free stream stagnation temperature, which is related to the thermal conductivity of the ''inert" mode, the dimensionless relaxation length, the ratio of the translational mode temperature to the temperature of the relaxing mode at the edge of the boundary layer, and the magnitude of the internal energy undergoing relaxation. An experiment is described whereby the thermal conductivity of the "inert" mode, which is unknown, may be determined from adiabatic wall temperature measurements.

This book was released on 1972 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program written in FORTRAN 4 language is presented which determines expansion-tube flow quantities for real test gases CO2, N2, O2, Ar, He, and H2, or mixtures of these gases, in thermochemical equilibrium. The effects of dissociation and first and second ionization are included. Flow quantities behind the incident shock into the quiescent test gas are determined from the pressure and temperature of the quiescent test gas in conjunction with: (1) incident-shock velocity, (2) static pressure immediately behind the incident shock, or (3) pressure and temperature of the driver gas (imperfect hydrogen or helium). The effect of the possible existence of a shock reflection at the secondary diaphragm of the expansion tube is included. Expansion-tube test-section flow conditions are obtained by performing an isentropic unsteady expansion from the conditions behind the incident shock or reflected shock to either the test-region velocity or the static pressure. Both a thermochemical-equilibrium expansion and a frozen expansion are included. Flow conditions immediately behind the bow shock of a model positioned at the test section are also determined. Results from the program are compared with preliminary experimental data obtained in the Langley 6-inch expansion tube.
