A Coupled Heat Transfer Calculation Strategy for Composite Cooling Liquid Rocket Engine

open access: yesAerospace, 2023
To better understand the characteristics of coupled heat transfer in liquid rocket engines, a calculation scheme is proposed in this paper. This scheme can simulate the coupled heat transfer processes, including combustion and flow in the thrust chamber,

Nomograms for Calculation of Heat Loss [PDF]

open access: yesBMJ, 1972
Two nomograms are presented. The first enables the mean surface and body temperatures and the body heat content of a patient of given weight to be determined from measurements of skin temperature at three sites and of the core (rectal) temperature. The second enables the change in heat content of such a patient to be determined from the change in mean ...

Saturated-liquid heat capacity calculation of alkanes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
An empirical model for the calculation of the heat capacity of alkanes is recommended. This model was tested and compared to known models (Luria–Benson and Rizicka–Domalski) using 68 sets with 1155 literature experimental heat capacity data of 39 ...
