總焓 的英文怎麼說
中文拼音 [zǒng]
總焓
英文
total enthalpy-
In order to apply the central scheme to higher mach number flows, the sensor about pressure or temperature are modified with some tvd - like properties. modification to van leer scheme about the energy component can preserve a constant total enthalpy in the steady flows
對vanleer格式中的能量分裂式進行改進，使其在定常流動中總焓守恆；採用統一的通量矢量函數，最大程度地實現了流場程序向量化，計算效率得以提高。There are great differences between ground test of a flight vehicle ' s aerodynamics and that of a dual - mode scramjet when ground test facilities are used to do experiments on a dual - mode scramjet engine, the components of incoming flow and its parameters, including total pressure, total temperature ( or total enthalpy ) and velocity must be simulated. at the same time, since the fuel ' s resident time within a combustor is very short, on the order of one millisecond, it is difficult to measure the flow - fields
進行雙模態沖壓發動機地面試驗研究時，必須要求試驗設備能模擬實際飛行條件下來流氣體的組分、總壓、總溫（或總焓）以及來流氣體的流動速度；同時由於燃料在燃燒室內駐留的時間很短，一般為毫秒量級，從而使流場物理量的測定顯得非常困難。
